[merged] mm-no-more-einval-from-proc-sys-vm-stat_refresh.patch removed from -mm tree

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The patch titled
     Subject: mm: no more EINVAL from /proc/sys/vm/stat_refresh
has been removed from the -mm tree.  Its filename was
     mm-no-more-einval-from-proc-sys-vm-stat_refresh.patch

This patch was dropped because it was merged into mainline or a subsystem tree

------------------------------------------------------
From: Hugh Dickins <hughd@xxxxxxxxxx>
Subject: mm: no more EINVAL from /proc/sys/vm/stat_refresh

EINVAL was good for drawing the refresher's attention to a warning in
dmesg, but became very tiresome when running test suites scripted with
"set -e": an underflow from a bug in one feature would cause unrelated
tests much later to fail, just because their /proc/sys/vm/stat_refresh
touch failed with that error.  Stop doing that.
