Hi Linus,

Here is the pull request on f2fs updates for v3.11.
Most of patches in this patch-set have been proposed to fix the
roll-forward mechanism significantly.

One of major fixes is related to little and big endian conversion, and
its errorneous symptom on powerpc was initially reported by Oded Gabbay.

Another one is that it has been revealed the pgbench regression reported
by phoronix was caused by one of fsync bug fixes in 3.10-rc1. In order
to restore the performance, one enhancement patch was introduced in this
patch-set, which is f2fs: recover wrong pino after checkpoint during
fsync.

One of new features is *xattr security labels* which is essential to the
SEandroid system.

Please consider pulling the following tag.
Thank you,

This patch-set includes the following major enhancement patches.
 o remount_fs callback function
 o restore parent inode number to enhance the fsync performance
 o xattr security labels
 o reduce the number of redundant lock/unlock data pages
 o avoid frequent write_inode calls

The other minor bug fixes are as follows.
 o endian conversion bugs
 o various bugs in the roll-forward recovery routine
