Re: [PATCH block/for-linus] writeback: fix syncing of I_DIRTY_TIME inodes

I had an unstable system when running latest Linus tree with Tejun's
patch applied on top. Nothing fishy in the logs after rebooting without
the patch, but remote access with ssh when patch applied did not work
(as if /home partition could not be read). This system has / as ext4 and
other partitions (including /home) as XFS. Trying to login on tty
instead of X resulted in hang of X. I could reboot with sysrq, but can't
do further tests at the moment.

Back to same tree without the patch resulted in normal system.
So just a heads up the patch doesn't seem OK in its current state.
Hi Tejun,
Have you been able to reproduce the failure? That sounds like an
unlikely failure mode for the patch.
Unfortunately (as it would be nice to understand what happened), no.
I reapplied the patch on top of rc7 and could not reproduce the
unstability after several reboots.

I will continue running with the patch and report if anything strange
appears again...
