linux/fs/f2fs
Linus Torvalds 4c1fad64ef In this round, we've investigated how f2fs deals with errors given by our fault
injection facility. With this, we could fix several corner cases. And, in order
 to improve the performance, we set inline_dentry by default and enhance the
 exisiting discard issue flow. In addition, we added f2fs_migrate_page for better
 memory management.
 
 = Enhancement =
  - set inline_dentry by default
  - improve discard issue flow
  - add more fault injection cases in f2fs
  - allow block preallocation for encrypted files
  - introduce migrate_page callback function
  - avoid truncating the next direct node block at every checkpoint
 
 = Bug fixes =
  - set page flag correctly between write_begin and write_end
  - missing error handling cases detected by fault injection
  - preallocate blocks regarding to 4KB alignement correctly
  - dentry and filename handling of encryption
  - lost xattrs of directories
