f2fs: clean up coding style and redundancy (2016-07-25 12:58:12 -0700)
----------------------------------------------------------------
The major change in this version is mitigating cpu overheads on write paths by
replacing redundant inode page updates with mark_inode_dirty calls. And we tried
to reduce lock contentions as well to improve filesystem scalability.
Other feature is setting F2FS automatically when detecting host-managed SMR.
= Enhancement =
- ioctl to move a range of data between files
- inject orphan inode errors
- avoid flush commands congestion
- support lazytime
= Bug fixes =
- return proper results for some dentry operations
- fix deadlock in add_link failure
- disable extent_cache for fcollapse/finsert
----------------------------------------------------------------
