Hi,

  Kernel fault injection framework have provided a a systematic
  way to support error injection via debugfs in the /sys/kernel/debug
  directory.

  Compared to the current fault injection by mount options and sysfs,
  fault injection framework can provide more easy used fault injection
  control means.

  Thus, this patchset try to use common fault injection for f2fs.

Yufen Yu (5):
  f2fs: extract f2fs root debugfs to init_f2fs_fs
  f2fs: use common fault injection frmework
  f2fs: replace function time_to_inject by f2fs_should_fail
  f2fs: get rid of stale fault injection code
  f2fs: update doc for f2fs fault injection
