Double decreased the count to trim caps which will cause failing to respond to cache pressure
When reaching mds cache size, mds will ask clients to trim its own caps. In ceph-fuse, it will recalculate current caps size for each loop, so it double decreases the loop counts. Hence at most time, ceph-fuse client only trims half of expected caps number. MDS often reports the warning of failing to respond to cache pressure and have to wait for asking client to trim caps next time.

Whoops, this got merged in way back then in January!
Looks like no backport got scheduled or anything; we'll see if it makes it — there are plenty of other reasons to upgrade to Jewel when using CephFS!
