udf: allow implicit blocksize specification during mount udf_fill_super() used udf_parse_options() to flag UDF_FLAG_BLOCKSIZE_SET when blocksize was specified otherwise used 512 bytes (bdev_logical_block_size) and 2048 bytes (UDF_DEFAULT_BLOCKSIZE) IOW both 1024 and 4096 specifications were required or resulted in "mount: wrong fs type, bad option, bad superblock on /dev/loop1" This patch loops through different block values but also updates udf_load_vrs() to return -EINVAL instead of 0 when udf_check_vsd() fails (and uopt->novrs = 0). The later being the reason for the RFC; we have that case when mounting a 4kb blocksize against other values but maybe VRS is not mandatory there ? Tested with 512, 1024, 2048 and 4096 blocksize Reported-by: Jan Kara <jack@suse.com> Signed-off-by: Fabian Frederick <fabf@skynet.be> Signed-off-by: Jan Kara <jack@suse.cz>
