Linus Torvalds 25c4e6c3f0 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.
