Hi all, this series decrufts various bits of vaguely mount / mount option related code. The background is the mount API from series, which currently is a lot more ugly than it should be do the way how we parse two mount options with arguments into local variables instead of directly into the mount structure. This series cleans that and a few nearby warts. Changes since v1: - document the behavior change for allocsize=0 - pick up the patch to remove the biosize option from the mount API series - remove the -o wsync allocsize hack entirely - remove the m_readio_* fields entirely - rename the m_writeio_* fields to m_allocio_* - more tweaks to xfs_parseargs - clean up printing the mount options
