udf: Fix loading of special inodes
Some UDF media have special inodes (like VAT or metadata partition inodes) whose link_count is 0. Thus commit 4071b9136223 (udf: Properly detect stale inodes) broke loading these inodes because udf_iget() started returning -ESTALE for them. Since we still need to properly detect stale inodes queried by NFS, create two variants of udf_iget() - one which is used for looking up special inodes (which ignores link_count == 0) and one which is used for other cases which return ESTALE when link_count == 0. Fixes: 4071b913622316970d0e1919f7d82b4403fec5f2 CC: stable@vger.kernel.org Signed-off-by: Jan Kara <jack@suse.cz>
