libceph: change ceph_osdmap_flag() to take osdc

2016-05-30T21:00:22Z

For the benefit of every single caller, take osdc instead of map. Also, now that osdc->osdmap can't ever be NULL, drop the check. Signed-off-by: Ilya Dryomov

ceph: make logical calculation functions return bool

2016-05-25T23:15:39Z

This patch makes serverl logical caculation functions return bool to improve readability due to these particular functions only using 0/1 as their return value. No functional change. Signed-off-by: Zhang Zhuoyu

ceph: using hash value to compose dentry offset

2016-05-25T23:15:36Z

If MDS sorts dentries in dirfrag in hash order, we use hash value to compose dentry offset. dentry offset is: (0xff << 52) | ((24 bits hash) << 28) | (the nth entry hash hash collision) This offset is stable across directory fragmentation. This alos means there is no need to reset readdir offset if directory get fragmented in the middle of readdir. Signed-off-by: Yan, Zheng

ceph: define 'end/complete' in readdir reply as bit flags

2016-05-25T23:15:35Z

Set a flag in readdir request, which indicates that client interprets 'end/complete' as bit flags. So that mds can reply additional flags in readdir reply. Signed-off-by: Yan, Zheng

libceph: replace ceph_monc_request_next_osdmap()

2016-05-25T23:15:30Z

... with a wrapper around maybe_request_map() - no need for two osdmap-specific functions. Signed-off-by: Ilya Dryomov

libceph: pool deletion detection

2016-05-25T23:15:29Z

This adds the "map check" infrastructure for sending osdmap version checks on CALC_TARGET_POOL_DNE and completing in-flight requests with -ENOENT if the target pool doesn't exist or has just been deleted. Signed-off-by: Ilya Dryomov

libceph: async MON client generic requests

2016-05-25T23:15:29Z

For map check, we are going to need to send CEPH_MSG_MON_GET_VERSION messages asynchronously and get a callback on completion. Refactor MON client to allow firing off generic requests asynchronously and add an async variant of ceph_monc_get_version(). ceph_monc_do_statfs() is switched over and remains sync.

libceph: support for checking on status of watch

2016-05-25T23:15:28Z

Implement ceph_osdc_watch_check() to be able to check on status of watch. Note that the time it takes for a watch/notify event to get delivered through the notify_wq is taken into account. Signed-off-by: Ilya Dryomov

libceph: support for sending notifies

2016-05-25T23:15:28Z

Implement ceph_osdc_notify() for sending notifies. Due to the fact that the current messenger can't do read-in into pagelists (it can only do write-out from them), I had to go with a page vector for a NOTIFY_COMPLETE payload, for now. Signed-off-by: Ilya Dryomov
