Subject: [PATCH 0/8] Clean up ext4's block free code paths

This patch series cleans up functions involved with freeing blocks.  It
removes functions that are only called by a single caller and folds them
into their caller, and makes the code a little easier to read.  It also
reduces ext4's code foot print slightly (by 136 bytes).  

Finally, it fixes a bug in the extents migration function, which was
missing calls to ext4_forget() when it frees the indirect blocks after
converting an inode to using extents.  This avoids potential file system
corruption after a crash while converting an entire filesystem to use
extents via "chattr -R +e /mntpt".

Theodore Ts'o (8):
  ext4: move ext4_forget() to ext4_jbd2.c
  ext4: fold ext4_journal_revoke() into ext4_forget()
  ext4: fold ext4_journal_forget() into ext4_forget()
  ext4: fold ext4_free_blocks() and ext4_mb_free_blocks()
  ext4: call ext4_forget() from ext4_free_blocks()
  ext4: print i_mode in octal in ext4 tracepoints
  ext4: add check for wraparound in ext4_data_block_valid()
  ext4: use ext4_data_block_valid() in ext4_free_blocks()
