Nice cleanups!

Hmm.. in my patch the deleted lines from inode.c matched
the added lines in indirect.c (-1 newline at end of file).
Your patch has:
 fs/ext4/indirect.c       | 1510 ++++++++++++++++++++++++++++++++++++++++++++++
 fs/ext4/inode.c          | 1486 ---------------------------------------------

This accounts for 28 lines added by header comment and includes in indirect.c
-1 newline at end of file, so where did 3 more lines go?
I am guessing these are just deleted newlines, but have no way of knowing.
Have you made other (maybe checkpatch) changes while moving or just
removed 'static'
from function declarations?
I am asking just in case I get 'git blamed' for it some day ;-)

Cheers,
Amir.
