2011-01-13cramfs: generate unique inode number for better inode cache usageStefani Seibold
Generate a unique inode numbers for any entries in the cram file system. For files which did not contain data's (device nodes, fifos and sockets) the offset of the directory entry inside the cramfs plus 1 will be used as inode number. The + 1 for the inode will it make possible to distinguish between a file which contains no data and files which has data, the later one has a inode value where the lower two bits are always 0. It also reimplements the behavior to set the size and the number of block to 0 for special file, which is the right value for empty files, devices, fifos and sockets As a little benefit it will be also more compatible which older mkcramfs, because it will never use the cramfs_inode->offset for creating a inode number for special files.

2011-01-13/proc/kcore: fix seekingDave Anderson
Commit 34aacb2920 ("procfs: Use generic_file_llseek in /proc/kcore") broke seeking on /proc/kcore. This changes it back to use default_llseek in order to restore the original behavior. The problem with generic_file_llseek is that it only allows seeks up to inode->i_sb->s_maxbytes, which is 2GB-1 on procfs, where the memory file offset values in the /proc/kcore PT_LOAD segments may exceed or start beyond that offset value. A similar revert was made for /proc/vmcore.

2011-01-13reiserfs: make sure va_end() is always called after va_start().Jesper Juhl
A call to va_start() must always be followed by a call to va_end() in the same function. In fs/reiserfs/prints.c::print_block() this is not always the case. If 'bh' is NULL we'll return without calling va_end(). One could add a call to va_end() before the 'return' statement, but it's nicer to just move the call to va_start() after the test for 'bh' being NULL.

2011-01-11ext4: fix trimming starting with block 0 with small blocksizeJan Kara
When s_first_data_block is not zero (which happens e.g. when block size is 1KB) and trim ioctl is called to start trimming from block 0, the math in ext4_get_group_no_and_offset() overflows. The overall result is that ioctl returns EINVAL which is kind of unexpected and we probably don't want userspace tools to bother with internal details of filesystem structure. So just silently increase starting offset (and shorten length) when starting block is below s_first_data_block.

This merge pulls the XFS master branch into the latest Linus master. This results in a merge conflict whose best fix is not obvious. I manually fixed the conflict, in "fs/xfs/xfs_iget.c". Dave Chinner had done work that resulted in RCU freeing of inodes separate from what Nick Piggin had done, and their results differed slightly in xfs_inode_free(). The fix updates Nick's call_rcu() with the use of VFS_I(), while incorporating needed updates to some XFS inode fields implemented in Dave's series. Dave's RCU callback function has also been removed. Signed-off-by: Alex Elder <aelder@sgi.com>

2011-01-10ext3: speed up file creates by optimizing rec_len functionsEric Sandeen
The addition of 64k block capability in the rec_len_from_disk and rec_len_to_disk functions added a bit of math overhead which slows down file create workloads needlessly when the architecture cannot even support 64k blocks, thanks to page size limits. Similar changes already exist in the ext4 codebase. The directory entry checking can also be optimized a bit by sprinkling in some unlikely() conditions to move the error handling out of line. bonnie++ sequential file creates on a 512MB ramdisk speeds up from about 77,000/s to about 82,000/s, about a 6% improvement.
