Subject: osd/: Retain the default osd_max_backfills limit to 1 for mClock
X-Git-Tag: v17.2.7~418^2~3
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=00db2d1b7bf848341576db7a7cb8094d2eae9cd2;p=ceph.git

osd/: Retain the default osd_max_backfills limit to 1 for mClock

The earlier limit of 3 was still aggressive enough to have an impact on
the client and other competing operations. Retain the current default
for mClock. This can be modified if necessary after setting the
osd_mclock_override_recovery_settings option.
