the ext2_permission function prototype in include/linux/ext2_fs.h is
never implemented. no big deal, just a little misleading. this appears
to be leftover from 2.2.
the ext2_notify_change function is implemented in fs/ext2/inode.c
but not used anywhere. this appears to be leftover from 2.2 when
ext2_notify_change was part of super_operations. now that the
corresponding functionality is provided by inode_operations->setattr,
ext2 lets vfs handle with generic inode_setattr function. so this
function appears to just waste space.
the patch below removes both. these are already removed from the -ac
tree.
thanks,
