From 85ccce43a3fc15a40ded6ae1603e3f68a17f4d24 Mon Sep 17 00:00:00 2001 From: Sage Weil Date: Wed, 17 Feb 2010 10:02:43 -0800 Subject: ceph: clean up readdir caps reservation Use a global counter for the minimum number of allocated caps instead of hard coding a check against readdir_max. This takes into account multiple client instances, and avoids examining the superblock mount options when a cap is dropped.
