From ad3bdefe877afb47480418fdb05ecd42842de65e Mon Sep 17 00:00:00 2001 From: Wu Fengguang Date: Wed, 11 Mar 2009 09:00:04 +0800 Subject: proc: fix kflags to uflags copying in /proc/kpageflags Fix kpf_copy_bit(src,dst) to be kpf_copy_bit(dst,src) to match the actual call patterns, e.g. kpf_copy_bit(kflags, KPF_LOCKED, PG_locked). This misplacement of src/dst only affected reporting of PG_writeback, PG_reclaim and PG_buddy. For others kflags==uflags so not affected.
