BKL-removal: convert ext2 over to use unlocked_ioctl
I checked ext2_ioctl and could not find anything in there that would need the BKL. So convert it over to use unlocked_ioctl Signed-off-by: Andi Kleen <ak@suse.de> Cc: Theodore Ts'o <tytso@mit.edu> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
