fs/ecryptfs/: possible cleanups
- make the following needlessly global code static: - crypto.c:ecryptfs_lower_offset_for_extent() - crypto.c:key_tfm_list - crypto.c:key_tfm_list_mutex - inode.c:ecryptfs_getxattr() - main.c:ecryptfs_init_persistent_file() - remove the no longer used mmap.c:ecryptfs_lower_page_cache - #if 0 the unused read_write.c:ecryptfs_read() Signed-off-by: Adrian Bunk <bunk@kernel.org> Cc: Michael Halcrow <mhalcrow@us.ibm.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
