f2fs: avoid to flush nat journal entries (2017-02-28 09:57:13 -0800)
----------------------------------------------------------------
for-f2fs-4.11
This round introduces several interesting features such as on-disk NAT bitmaps,
IO alignment, and a discard thread. And it includes a couple of major bug fixes
as below.
== Enhancement ==
- introduce on-disk bitmaps to avoid scanning NAT blocks when getting free nids
- support IO alignment to prepare open-channel SSD integration in future
- introduce a discard thread to avoid long latency during checkpoint and fstrim
- use SSR for warm node and enable inline_xattr by default
- introduce in-memory bitmaps to check FS consistency for debugging
- improve write_begin by avoiding needless read IO
== Bug fix ==
- fix broken zone_reset behavior for SMR drive
- fix wrong victim selection policy during GC
- fix missing behavior when preparing discard commands
- fix bugs in atomic write support and fiemap
- workaround to handle multiple f2fs_add_link calls having same name
And it includes a bunch of clean-up patches as well.
