The libfc provides more flexibility and with that we can monitor some more FC specific stats for FC exches or FCP error cases, this patch add such new FC stats. The patch adds *only* FC specific new stats to existing fc_host attribute container. Added stats names are self explanatory as existing FC stats already has, however anyway still added commentary along their definition to describe them.

2012-07-20UBIFS: remove invalid reference to list iterator variableJulia Lawall
If list_for_each_entry, etc complete a traversal of the list, the iterator variable ends up pointing to an address at an offset from the list head, and not a meaningful structure. Thus this value should not be used after the end of the iterator. Replace a field access from orphan by NULL in two places. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ identifier c; expression E; iterator name list_for_each_entry; statement S; @@ list_for_each_entry(c,...) { ... when != break; when forall when strict } ... ( c = E | *c ) // </smpl> Artem: fortunately, this did not cause any issues because we iterate the orphan list using the elements count, so we never dereferenced the corrupted pointer. This is why I do not send this patch to -stable. But otherwise - well spotted! Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@linux.intel.com>
2012-07-20UBIFS: simplify reply code a bitArtem Bityutskiy
In the log reply code we assume that 'c->lhead_offs' is known and may be non-zero, which is not the case because we do not store it in the master node and have to find out by scanning on every mount. Knowing this fact allows us to simplify the log scanning loop a bit and remove a couple of unneeded local variables. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@linux.intel.com>
2012-07-20UBIFS: add debugfs knob to switch to R/O modeArtem Bityutskiy
This patch adds another debugfs knob which switches UBIFS to R/O mode. I needed it while trying to reproduce the 'first log node is not CS node' bug. Without this debugfs knob you have to perform a power cut to repruduce the bug. The knob is named 'ro_error' and all it does is it sets the 'ro_error' UBIFS flag which makes UBIFS disallow any further writes - even write-back will fail with -EROFS. Useful for debugging.

2012-07-20UBIFS: fix a bug in empty space fix-upArtem Bityutskiy
UBIFS has a feature called "empty space fix-up" which is a quirk to work-around limitations of dumb flasher programs. Namely, of those flashers that are unable to skip NAND pages full of 0xFFs while flashing, resulting in empty space at the end of half-filled eraseblocks to be unusable for UBIFS. This feature is relatively new (introduced in v3.0). The fix-up routine (fixup_free_space()) is executed only once at the very first mount if the superblock has the 'space_fixup' flag set (can be done with -F option of mkfs.ubifs). It basically reads all the UBIFS data and metadata and writes it back to the same LEB. The routine assumes the image is pristine and does not have anything in the journal. There was a bug in 'fixup_free_space()' where it fixed up the log incorrectly. All but one LEB of the log of a pristine file-system are empty. And one contains just a commit start node. And 'fixup_free_space()' just unmapped this LEB, which resulted in wiping the commit start node. As a result, some users were unable to mount the file-system next time with the following symptom: UBIFS error (pid 1): replay_log_leb: first log node at LEB 3:0 is not CS node UBIFS error (pid 1): replay_log_leb: log error detected while replaying the log at LEB 3:0 The root-cause of this bug was that 'fixup_free_space()' wrongly assumed that the beginning of empty space in the log head (c->lhead_offs) was known on mount. However, it is not the case - it was always 0. UBIFS does not store in it the master node and finds out by scanning the log on every mount. The fix is simple - just pass commit start node size instead of 0 to 'fixup_leb()'.

2012-07-20dma: sh: use an integer slave ID to improve API compatibilityGuennadi Liakhovetski
Initially struct shdma_slave has been introduced with the only member - an unsigned slave ID - to describe common properties of DMA slaves in an extensible way. However, experience shows, that a slave ID is indeed the only parameter, needed to identify DMA slaves. This is also, what is used by the core dmaengine API in struct dma_slave_config. We switch to using the slave_id directly, instead of passing a pointer to struct shdma_slave to improve compatibility with the core. We also make the slave_id signed for easier error checking.

Userspace uses long in quite a few places more than the kernel. Which gives me neat proof that I'm the only guy on this side of the galaxy who ever tried to run glxgears on a 64bit machine with sis graphics on linux. Note that the longs in drm_sis_mem_t aren't aligned properly, so this won't even work with 32bit userspace on 64bit kernel as-is. Hence the patch can't break that, either. Nope, I'm not nuts enough to write the 32bit ioctl compat layer for this and test it with some wine app. Even though hunting the ebay dungeons for a sis card actually supported by the mesa drivers casts some doubts on this ...

Switch over to the idlelock duct-tape on hope that works better. I've fired up my i815 and now closing glxgears doesn't take 5 seconds anymore. \o/ The original problem with that was that I've moved it ahead in the series so that it could be included despite some patches not being ready quite yet. The little problem is that this patch required some of the previous rework to work correctly.

2012-07-19drm/fb-helper: delay hotplug handling when partially boundDaniel Vetter
Ok, this requires quite a dance to actually hit: 1) We plug in a 2nd screen, enable it in both X and (by vt-switching) in the fbcon. 2) We disable that screen again in with xrandr. 3) We vt-switch again, so that fbcon displays on the 2nd screen, but X on the first screen. This obviously needs a driver that doesn't switch off unused functions when regaining the VT. 3) When X controls the vt, we unplug that screen. Now drm_fb_helper_hotplug_event we noticed that that some crtcs are bound, but because we still have the fbcon on the 2nd screeen we also have bound set. Which means the fbcon wrongly assumes it's in control of everything an happily disables the output on the 2nd screen, but enables its fb on the first screen. Work around this issue by counting how many crtcs are bound and how many are bound to fbcon and assuming that when fbcon isn't bound to all of them, it better not touch the output configuration. Conceptually this is the same as only restoring the fbcon output configuration on the driver's ->lastclose, when we're sure that no one else is using kms. So this should be consistent with existing kms drivers. Chris has created a separate patch for the intel ddx, but I think we should fix this issue here regardless - the fbcon messing with the output config while it's not fully in control simply isn't a too polite behaviour.

Instead of only setting the FCOE segmentation offload and CRC offload flags if we enable FCoE, we could just set them always since there are no modifications needed to the hardware or adapter FCoE structure in order to use these features.

2012-07-19ixgbe: Only enable anti-spoof on VF poolsAlexander Duyck
The current logic is enabling anti-spoof on all pools and then clearing anti-spoof on just the first PF pool. The correct approach is to only set anti-spoof on the VF pools and to leave all of the PF pools unchecked.

2012-07-19ixgbe: Make FCoE allocation and configuration closer to how rings workAlexander Duyck
This patch changes the behavior of the FCoE configuration so that it is much closer to how the main body of the ixgbe driver works for ring allocation. The first piece is the ixgbe_fcoe_ddp_enable/disable calls. These allocate the percpu values and if successful set the fcoe_ddp_xid value indicating that we can support DDP. The next piece is the ixgbe_setup/free_ddp_resources calls. These are called on open/close and will allocate and free the DMA pools. Finally ixgbe_configure_fcoe is now just register configuration. It can go through and enable the registers for the FCoE redirection offload, and FIP configuration without any interference from the DDP pool allocation. The net result of all this is two fold. First it adds a certain amount of exception handling. So for example if ixgbe_setup_fcoe_resources fails we will actually generate an error in open and refuse to bring up the interface. Secondly it provides a much more graceful failure case than the previous model which would skip setting up the registers for FCoE on failure to allocate DDP resources leaving no Rx functionality enabled instead of just disabling DDP.

2012-07-19ixgbe: Merge all FCoE percpu values into a single structureAlexander Duyck
This change merges the 2 statistics values for noddp and noddp_ext_buff and the dma_pool into a single structure that can be allocated per CPU. The advantages to this are several fold. First we only need to do one alloc_percpu call now instead of 3, so that means less overhead for handling memory allocation failures. Secondly in the case of ixgbe_fcoe_ddp_setup we only need to call get_cpu once which makes things a bit cleaner since we can drop a put_cpu() from the exception path.

2012-07-19ixgbe: Cleanup configuration of FCoE registersAlexander Duyck
This change makes it so we always use the FCoE redirection table. We just set all 8 entries to the same value in the case of only having one queue for FCoE.
