Subject[PATCHv6 6/9] sysv: do not mark superblock dirty on remount
Date
From: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>

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.
