afr: make heal info lockless
Changes in locks xlator: Added support for per-domain inodelk count requests. Caller needs to set GLUSTERFS_MULTIPLE_DOM_LK_CNT_REQUESTS key in the dict and then set each key with name 'GLUSTERFS_INODELK_DOM_PREFIX:<domain name>'. In the response dict, the xlator will send the per domain count as values for each of these keys. Changes in AFR: Replaced afr_selfheal_locked_inspect() with afr_lockless_inspect(). Logic has been added to make the latter behave same as the former, thus not breaking the current heal info output behaviour. fixes: bz#1774011 Change-Id: I9ae08ce768b39aeb6ee230207b5b7fa744176952 Signed-off-by: Ravishankar N <ravishankar@redhat.com>
