Subject: [PATCH] jiffies handling in md.c
Date: Mon, 29 Nov 2004 00:22:40 +0100 [thread overview]
Message-ID: <41AA5DC0.20403@stud.feec.vutbr.cz> (raw)

Hello,
md_do_sync in md.c doesn't handle jiffies overflow correctly.
The attached patch fixes this by changing the comparison to use the
time_after_eq macro.
Only compile-tested.
