Subject: mds: add retry request to MDSRank wait queue rather via finisher
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=02735a362c685bfdb975ab86c9b042a8792f75b0;p=ceph.git

mds: add retry request to MDSRank wait queue rather via finisher

C_MDS_RetryRequest inherits from MDSInternalContext which does not
acquire mds_lock by itself. Adding to MDSRank wait queue will process
this via the progress thread which completes the context with mds_lock
acquired.
