From 3601ba27353a968df843454e4b81155376682505 Mon Sep 17 00:00:00 2001 From: Artem Bityutskiy Date: Mon, 18 Oct 2010 08:32:35 +0300 Subject: [PATCH] UBIFS: do not forget to cancel timers This is a bug-fix: when we unmount, and we are currently in R/O mode because of an error - we do not sync write-buffers, which means we also do not cancel write-buffer timers we may possibly have armed. This patch fixes the issue. The issue can easily be reproduced by enabling UBIFS failure debug mode (echo 4 > /sys/module/ubifs/parameters/debug_tsts) and unmounting as soon as a failure happen. At some point the system oopses because we have an armed hrtimer but UBIFS is unmounted already. Signed-off-by: Artem Bityutskiy --- Reading git-format-patch failed
