sysv: do not mark superblock dirty on remount
No need to mark the superblock as dirty in sysv_remount, synchronize it instead (only if mounting R/O). I did not find any docs about this file-system, and I have no possibility to test my changes. Thus, this is untested. I see other issues in sysv, e.g., why sysv_sync_fs writes only in the FSTYPE_SYSV4 case? However, it marks its SB bh's dirty for all types, and does not wait for them ever. With zero docs I'm unable to fix this. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
