Subject: [PATCH 12/13] xfs: remove a stale comment from xfs_file_aio_write_checks()

From: Eric Biggers <ebiggers@...gle.com>

The comment in xfs_file_aio_write_checks() about calling file_modified()
after dropping the ilock doesn't make sense, because the code that
unconditionally acquires and drops the ilock was removed by
commit 467f78992a07 ("xfs: reduce ilock hold times in
xfs_file_aio_write_checks").

Remove this outdated comment.
