[PATCH] xfs: Fix 64-bit division on 32-bit in xlog_state_switch_iclogs()

From: Geert Uytterhoeven
Date: Thu Jun 10 2021 - 07:00:20 EST


On 32-bit (e.g. m68k):

ERROR: modpost: "__udivdi3" [fs/xfs/xfs.ko] undefined!

Fix this by using a uint32_t intermediate, like before.

Reported-by: noreply@xxxxxxxxxxxxxx
Fixes: 7660a5b48fbef958 ("xfs: log stripe roundoff is a property of the log")
