2011-05-26flex_array: avoid divisions when accessing elementsJesse Gross
On most architectures division is an expensive operation and accessing an element currently requires four of them. This performance penalty effectively precludes flex arrays from being used on any kind of fast path. However, two of these divisions can be handled at creation time and the others can be replaced by a reciprocal divide, completely avoiding real divisions on access.

2011-05-26Btrfs: setup free ino caching in a more asynchronous wayLi Zefan
For a filesystem that has lots of files in it, the first time we mount it with free ino caching support, it can take quite a long time to setup the caching before we can create new files. Here we fill the cache with [highest_ino, BTRFS_LAST_FREE_OBJECTID] before we start the caching thread to search through the extent tree.

2011-05-26block: always allocate genhd->ev if check_events is implementedTejun Heo
9fd097b149 (block: unexport DISK_EVENT_MEDIA_CHANGE for legacy/fringe drivers) removed DISK_EVENT_MEDIA_CHANGE from legacy/fringe block drivers which have inadequate ->check_events(). Combined with earlier change 7c88a168da (block: don't propagate unlisted DISK_EVENTs to userland), this enables using ->check_events() for internal processing while avoiding enabling in-kernel block event polling which can lead to infinite event loop. Unfortunately, this made many drivers including floppy without any bit set in disk->events and ->async_events in which case disk_add_events() simply skipped allocation of disk->ev, which disables whole event handling. As ->check_events() is still used during open processing for revalidation, this can lead to open failure. This patch always allocates disk->ev if ->check_events is implemented. In the long term, it would make sense to simply include the event structure inline into genhd as it's now used by virtually all block devices.

2011-05-26brd: export module parametersNamhyung Kim
Export 'rd_nr', 'rd_size' and 'max_part' parameters to sysfs so user can know that how many devices are allowed, how big each device is and how many partitions are supported. If 'max_part' is 0, it means simply the device doesn't support partitioning. Also note that 'max_part' can be adjusted to power of 2 minus 1 form if needed. User should check this value after the module loading if he/she want to use that number correctly (i.e. fdisk, mknod, etc.).

2011-05-26brd: limit 'max_part' module param to DISK_MAX_PARTSNamhyung Kim
The 'max_part' parameter controls the number of maximum partition a brd device can have. However if a user specifies very large value it would exceed the limitation of device minor number and can cause a kernel panic (or, at least, produce invalid device nodes in some cases). On my desktop system, following command kills the kernel.

2011-05-26Fix build with !HUGETLBFSLinus Torvalds
I stupidly broke the case of CONFIG_HUGETLBFS=n when doing the conversion to vm_flags_t in commit ca16d140af91 ("mm: don't access vm_flags as 'int'"). And my 'allyesconfig' build didn't find it, for obvious reasons.. Include <linux/mm_types.h> in <linux/hugetlb.h>. The problem could have been avoided by just turning the hugetlb_file_setup() error wrapper into a macro, but mm_types.h is a reasonable include in this file.

As reported by Ingo Molnar, we still have configuration combinations where use of the WARN_RATELIMIT interfaces break the build because dependencies don't get met. Instead of going down the long road of trying to make it so that ratelimit.h can get included by kernel.h or asm-generic/bug.h, just move the interface into ratelimit.h and make users have to include that.

Weiping Pan noticed that the module option description for xmit_hash_policy was incorrect and was nice enough to post a patch to fix it. The text was correct, but created a line over 80 characters and I would rather not add those. I realized I could take a few minutes and clean up all the descriptions and things would look much better. This is the result. Based on patch from Weiping Pan <panweiping3@gmail.com>.

2011-05-26[CIFS] When mandatory encryption on share, fail mountSteve French
When mandatory encryption is configured in samba server on a share (smb.conf parameter "smb encrypt = mandatory") the server will hang up the tcp session when we try to send the first frame after the tree connect if it is not a QueryFSUnixInfo, this causes cifs mount to hang (it must be killed with ctl-c). Move the QueryFSUnixInfo call earlier in the mount sequence, and check whether the SetFSUnixInfo fails due to mandatory encryption so we can return a sensible error (EACCES) on mount. In a future patch (for 2.6.40) we will support mandatory encryption. CC: Stable <stable@kernel.org> Reviewed-by: Pavel Shilovsky <piastry@etersoft.ru> Signed-off-by: Steve French <sfrench@us.ibm.com>
