Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/sage/ceph-client

2014-06-13T06:06:23Z

Pull Ceph updates from Sage Weil: "This has a mix of bug fixes and cleanups. Alex's patch fixes a rare race in RBD. Ilya's patches fix an ENOENT check when a second rbd image is mapped and a couple memory leaks. Zheng fixes several issues with fragmented directories and multiple MDSs. Josh fixes a spin/sleep issue, and Josh and Guangliang's patches fix setting and unsetting RBD images read-only. Naturally there are several other cleanups mixed in for good measure" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/sage/ceph-client: (23 commits) rbd: only set disk to read-only once rbd: move calls that may sleep out of spin lock range rbd: add ioctl for rbd ceph: use truncate_pagecache() instead of truncate_inode_pages() ceph: include time stamp in every MDS request rbd: fix ida/idr memory leak rbd: use reference counts for image requests rbd: fix osd_request memory leak in __rbd_dev_header_watch_sync() rbd: make sure we have latest osdmap on 'rbd map' libceph: add ceph_monc_wait_osdmap() libceph: mon_get_version request infrastructure libceph: recognize poolop requests in debugfs ceph: refactor readpage_nounlock() to make the logic clearer mds: check cap ID when handling cap export message ceph: remember subtree root dirfrag's auth MDS ceph: introduce ceph_fill_fragtree() ceph: handle cap import atomically ceph: pre-allocate ceph_cap struct for ceph_add_cap() ceph: update inode fields according to issued caps rbd: replace IS_ERR and PTR_ERR with PTR_ERR_OR_ZERO ...

libceph: add ceph_monc_wait_osdmap()

2014-06-06T01:29:57Z

Add ceph_monc_wait_osdmap(), which will block until the osdmap with the specified epoch is received or timeout occurs. Export both of these as they are going to be needed by rbd. Signed-off-by: Ilya Dryomov Reviewed-by: Sage Weil

libceph: mon_get_version request infrastructure

2014-06-06T01:29:57Z

Add support for mon_get_version requests to libceph. This reuses much of the ceph_mon_generic_request infrastructure, with one exception. Older OSDs don't set mon_get_version reply hdr->tid even if the original request had a non-zero tid, which makes it impossible to lookup ceph_mon_generic_request contexts by tid in get_generic_reply() for such replies. As a workaround, we allocate a reply message on the reply path. This can probably interfere with revoke, but I don't see a better way. Signed-off-by: Ilya Dryomov Reviewed-by: Sage Weil

ceph: update inode fields according to issued caps

2014-06-06T01:29:52Z

Cap message and request reply from non-auth MDS may carry stale information (corresponding locks are in LOCK states) even they have the newest inode version. So client should update inode fields according to issued caps. Signed-off-by: Yan, Zheng

Announce our support for osdmaps with non-default primary affinity values. Signed-off-by: Ilya Dryomov Reviewed-by: Alex Elder

libceph: return primary from ceph_calc_pg_acting()

2014-04-05T04:08:14Z

In preparation for adding support for primary_temp, stop assuming primaryness: add a primary out parameter to ceph_calc_pg_acting() and change call sites accordingly. Primary is now specified separately from the order of osds in the set. Signed-off-by: Ilya Dryomov Reviewed-by: Alex Elder

libceph: switch ceph_calc_pg_acting() to new helpers

Switch ceph_calc_pg_acting() to new helpers: pg_to_raw_osds(), raw_to_up_osds() and apply_temps(). Signed-off-by: Ilya Dryomov Reviewed-by: Alex Elder
