  f2fs: stop GC when the victim becomes fully valid (2019-11-25 10:01:28 -0800)

----------------------------------------------------------------
f2fs-for-5.5-rc1

In this round, we've introduced fairly small number of patches as below.

Enhancement:
 - improve the in-place-update IO flow
 - allocate segment to guarantee no GC for pinned files

Bug fix:
 - fix updatetime in lazytime mode
 - potential memory leak in f2fs_listxattr
 - record parent inode number in rename2 correctly
 - fix deadlock in f2fs_gc along with atomic writes
 - avoid needless data migration in GC
