Subject: RDS: IB: fix the rds_ib_fmr_wq kick call
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=2e1d6b813ac146db1e33ebb9b90441012dde4952;p=openwrt%2Fstaging%2Fblogic.git

RDS: IB: fix the rds_ib_fmr_wq kick call

RDS IB mr pool has its own workqueue 'rds_ib_fmr_wq', so we need
to use queue_delayed_work() to kick the work. This was hurting
the performance since pool maintenance was less often triggered
from other path.
