Merge tag 'f2fs-for-3.18' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs
Pull f2fs updates from Jaegeuk Kim: "This patch-set introduces a couple of new features such as large sector size, FITRIM, and atomic/volatile writes. Several patches enhance power-off recovery and checkpoint routines. The fsck.f2fs starts to support fixing corrupted partitions with recovery hints provided by this patch-set. Summary: - retain some recovery information for fsck.f2fs - enhance checkpoint speed - enhance flush command management - bug fix for lseek - tune in-place-update policies - enhance roll-forward speed - revisit all the roll-forward and fsync rules - support larget sector size - support FITRIM - support atomic and volatile writes And several clean-ups and bug fixes are included" * tag 'f2fs-for-3.18' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs: (42 commits) f2fs: support volatile operations for transient data f2fs: support atomic writes f2fs: remove unused return value f2fs: clean up f2fs_ioctl functions f2fs: potential shift wrapping buf in f2fs_trim_fs() f2fs: call f2fs_unlock_op after error was handled f2fs: check the use of macros on block counts and addresses f2fs: refactor flush_nat_entries to remove costly reorganizing ops f2fs: introduce FITRIM in f2fs_ioctl f2fs: introduce cp_control structure f2fs: use more free segments until SSR is activated f2fs: change the ipu_policy option to enable combinations f2fs: fix to search whole dirty segmap when get_victim f2fs: fix to clean previous mount option when remount_fs f2fs: skip punching hole in special condition f2fs: support large sector size f2fs: fix to truncate blocks past EOF in ->setattr f2fs: update i_size when __allocate_data_block f2fs: use MAX_BIO_BLOCKS(sbi) f2fs: remove redundant operation during roll-forward recovery ...
