2017-09-01xfs: remove the ip argument to xfs_defer_finishChristoph Hellwig
And instead require callers to explicitly join the inode using xfs_defer_ijoin. Also consolidate the defer error handling in a few places using a goto label.

2017-09-01xfs: refactor xfs_trans_rollChristoph Hellwig
Split xfs_trans_roll into a low-level helper that just rolls the actual transaction and a new higher level xfs_trans_roll_inode that takes care of logging and rejoining the inode. This gets rid of the NULL inode case, and allows to simplify the special cases in the deferred operation code. Signed-off-by: Christoph Hellwig <hch@lst.de> Reviewed-by: Darrick J.

2017-09-01xfs: check for race with xfs_reclaim_inode() in xfs_ifree_cluster()Omar Sandoval
After xfs_ifree_cluster() finds an inode in the radix tree and verifies that the inode number is what it expected, xfs_reclaim_inode() can swoop in and free it. xfs_ifree_cluster() will then happily continue working on the freed inode. Most importantly, it will mark the inode stale, which will probably be overwritten when the inode slab object is reallocated, but if it has already been reallocated then we can end up with an inode spuriously marked stale. In 8a17d7ddedb4 ("xfs: mark reclaimed inodes invalid earlier") we added a second check to xfs_iflush_cluster() to detect this race, but the similar RCU lookup in xfs_ifree_cluster() needs the same treatment.

2017-09-01xfs: evict all inodes involved with log redo itemDarrick J. Wong
When we introduced the bmap redo log items, we set MS_ACTIVE on the mountpoint and XFS_IRECOVERY on the inode to prevent unlinked inodes from being truncated prematurely during log recovery. This also had the effect of putting linked inodes on the lru instead of evicting them. Unfortunately, we neglected to find all those unreferenced lru inodes and evict them after finishing log recovery, which means that we leak them if anything goes wrong in the rest of xfs_mountfs, because the lru is only cleaned out on unmount. Therefore, evict unreferenced inodes in the lru list immediately after clearing MS_ACTIVE.

2017-09-01perf stat: Only auto-merge events that are PMU aliasesArnaldo Carvalho de Melo
Peter reported that when he explicitely asked for multiple events with the same name on the command line it got coalesced into just one line, i.e.: # perf stat -e cycles -e cycles -e cycles usleep 1 Performance counter stats for 'usleep 1': 3,269,652 cycles 0.000884123 seconds time elapsed # And while there is the --no-merges option to disable that auto-merging, this is a blunt change in behaviour for such explicit request, so change the code so that this auto merging is done only when handling the multi PMU aliases with the same name that introduced this coalescing, restoring the previous behaviour for the explicit case: # perf stat -e cycles -e cycles -e cycles usleep 1 Performance counter stats for 'usleep 1': 1,472,837 cycles 1,472,837 cycles 1,472,837 cycles 0.001764870 seconds time elapsed # Reported-by: Peter Zijlstra <peterz@infradead.org> Acked-by: Andi Kleen <ak@linux.intel.com> Acked-by: Jiri Olsa <jolsa@kernel.org> Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: Mark Rutland <mark.rutland@arm.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Wang Nan <wangnan0@huawei.com> Fixes: 430daf2dc7af ("perf stat: Collapse identically named events") Link: http://lkml.kernel.org/r/20170831184122.GK4831@kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

2017-09-01perf vendor events powerpc: Remove duplicate eventsSukadev Bhattiprolu
Some POWER PMU event names have multiple/alternate event codes. These alternate event codes were listed in the POWER9 JSON files for reference. But the perf tool does not seem to handle duplicates cleanly. 'perf list' shows such duplicate events only once, but 'perf stat' ends up counting the first event code twice, multiplexing if necessary and we end up with double the event counts.

2017-09-01perf test powerpc: Fix 'Object code reading' testRavi Bangoria
'Object code reading' test always fails on powerpc guest. Two reasons for the failure are: 1. When elf section is too big (size beyond 'unsigned int' max value). objdump fails to disassemble from such section. This was fixed with commit 0f6329bd7fc ("binutils/objdump: Fix disassemble for huge elf sections") in binutils. 2. When the sample is from hypervisor. Hypervisor symbols can not be resolved within guest and thus thread__find_addr_map() fails for such symbols. Fix this by ignoring hypervisor symbols in the test.

2017-09-01net: mdio-mux: fix unbalanced put_deviceCorentin Labbe
mdio_mux_uninit() call put_device (unconditionally) because of of_mdio_find_bus() in mdio_mux_init. But of_mdio_find_bus is only called if mux_bus is empty. If mux_bus is set, mdio_mux_uninit will print a "refcount_t: underflow" trace. This patch add a get_device in the other branch of "if (mux_bus)".

2017-09-01bridge: switchdev: Clear forward mark when transmitting packetIdo Schimmel
Commit 6bc506b4fb06 ("bridge: switchdev: Add forward mark support for stacked devices") added the 'offload_fwd_mark' bit to the skb in order to allow drivers to indicate to the bridge driver that they already forwarded the packet in L2. In case the bit is set, before transmitting the packet from each port, the port's mark is compared with the mark stored in the skb's control block. If both marks are equal, we know the packet arrived from a switch device that already forwarded the packet and it's not re-transmitted. However, if the packet is transmitted from the bridge device itself (e.g., br0), we should clear the 'offload_fwd_mark' bit as the mark stored in the skb's control block isn't valid. This scenario can happen in rare cases where a packet was trapped during L3 forwarding and forwarded by the kernel to a bridge device.

2017-09-01Merge branch 'mvpp2-optional-PHYs-and-GoP-link-irq'David S. Miller
Antoine Tenart says: ==================== net: mvpp2: optional PHYs and GoP link irq This series aims at making the driver work when no PHY is connected between a port and the physical layer and not described as a fixed-phy. This is useful for some usecases such as when a switch is connected directly to the serdes lanes. It can also be used for SFP ports on the 7k-db and 8k-db while waiting for the phylink support to land in (which should be part of another series). This series makes the phy optional in the PPv2 driver, and then adds the support for the GoP port link interrupt to handle link status changes on such ports. This was tested using the SFP ports on the 7k-db and 8k-db boards. Since v1: - Now use phy_interface_mode_is_rgmii() in the GoP link patch. - Added one cosmetic patch to take advantage of phy_interface_mode_is_rgmii() in the whole PPv2 driver. ==================== Signed-off-by: David S.

This patch adds the GoP link interrupt support for when a port isn't connected to a PHY. Because of this the phylib callback is never called and the link status management isn't done.

2017-09-01net: mvpp2: make the phy optionalAntoine Tenart
There is not necessarily a PHY between the GoP and the physical port. However, the driver currently makes the "phy" property mandatory, contrary to what is stated in the device tree bindings. This patch makes the PHY optional, and aligns the PPv2 driver on its device tree documentation. However if a PHY is provided, the GoP link interrupt won't be used. With this patch switches directly connected to the serdes lanes and SFP ports on the Armada 8040-db and Armada 7040-db can be used if the link interrupt is described in the device tree.
