f2fs: should unset atomic flag after successful commit (2016-01-11 15:56:44 -0800)
----------------------------------------------------------------
Regarding to the new features, this patch series adds two ioctls to control
cached data and fragmented files.
And, the other most parts are trying to fix missing error cases and bugs that
we have not covered so far. The specific changes are summarized below.
= Enhancement =
- support an ioctl to execute online file defragmentation
- support an ioctl to flush cached data
- speed up shrinkg extent_cache entries
- handle broken superblock
- refector dirty inode management infra
- revisit f2fs_map_blocks to handle more cases
- reduce global lock coverage
- add detecting user's idle time
= Major bug fix =
- fix data race condition on cached nat entries
- fix error cases of volatile and atomic writes
