Zloop is file system backed and thus needs to sync the underlying file system to persist data. Set BLK_FEAT_WRITE_CACHE so that the block layer actually send flush commands, and fix the flush implementation as sync_filesystem requires s_umount to be held and the code currently misses that. Fixes: eb0570c ("block: new zoned loop block device driver") Signed-off-by: Christoph Hellwig <hch@lst.de> Reviewed-by: Damien Le Moal <dlemoal@kernel.org>
Zloop uses a command option parser for all control commands, but most options are only valid for adding a new device. Check for incorrectly specified options in the remove handler.
