ext2: Implement freezing
The only missing piece to make freezing work reliably with ext2 is to stop iput() of unlinked inode from deleting the inode on frozen filesystem. So add a necessary protection to ext2_evict_inode(). We also provide appropriate ->freeze_fs and ->unfreeze_fs functions. Signed-off-by: Jan Kara <jack@suse.cz> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
