Subject: ceph: remove unneeded test in try_flush_caps
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=27b0a392095d30e452772d4ae636150fd7f2172d;p=openwrt%2Fstaging%2Fblogic.git

ceph: remove unneeded test in try_flush_caps

cap->session is always non-NULL, so we can just do a single test for
equality w/o testing explicitly for a NULL pointer.
