From 719f2c879f4dda7d7f303bd387d37cd96db29d31 Mon Sep 17 00:00:00 2001 From: Artem Bityutskiy Date: Mon, 5 Jul 2010 15:15:04 +0300 Subject: [PATCH] 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.
