ceph: factor out libceph from Ceph file system

2010-10-20T22:37:28+00:00

This factors out protocol and low-level storage parts of ceph into a separate libceph module living in net/ceph and include/linux/ceph. This is mostly a matter of moving files around. However, a few key pieces of the interface change as well: - ceph_client becomes ceph_fs_client and ceph_client, where the latter captures the mon and osd clients, and the fs_client gets the mds client and file system specific pieces. - Mount option parsing and debugfs setup is correspondingly broken into two pieces. - The mon client gets a generic handler callback for otherwise unknown messages (mds map, in this case). - The basic supported/required feature bits can be expanded (and are by ceph_fs_client). No functional change, aside from some subtle error handling cases that got cleaned up in the refactoring process. Signed-off-by: Sage Weil

ceph: fix decoding of pool snap info

2010-08-02T18:10:07+00:00

The pool info contains a vector for snap_info_t, not snap ids. This fixes the broken decoding, which would declare teh update corrupt when a pool snapshot was created. Signed-off-by: Sage Weil

ceph: print useful error message when crush rule not found

2010-08-02T03:11:42+00:00

Include the crush_ruleset in the error message. Signed-off-by: Sage Weil

ceph: fix pg_mapping leak on pg_temp updates

2010-07-23T17:02:06+00:00

Free the ceph_pg_mapping structs when they are removed from the pg_temp rbtree. Also fix a leak in the __insert_pg_mapping() error path. Signed-off-by: Sage Weil

ceph: add kfree() to error path

2010-07-08T15:03:24+00:00

We leak a "pi" on this error path. Signed-off-by: Dan Carpenter Signed-off-by: Sage Weil

ceph: fix crush map update decoding

2010-06-17T17:22:48+00:00

If the incremental osdmap has a new crush map, advance the position after decoding so that we can parse the rest of the osdmap properly. Signed-off-by: Sage Weil

fs/ceph: Use ERR_CAST

2010-05-29T16:12:41+00:00

Use ERR_CAST(x) rather than ERR_PTR(PTR_ERR(x)). The former makes more clear what is the purpose of the operation, which otherwise looks like a no-op. In the case of fs/ceph/inode.c, ERR_CAST is not needed, because the type of the returned value is the same as the type of the enclosing function. The semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // @@ type T; T x; identifier f; @@ T f (...) { <+... - ERR_PTR(PTR_ERR(x)) + x ...+> } @@ expression x; @@ - ERR_PTR(PTR_ERR(x)) + ERR_CAST(x) // Signed-off-by: Julia Lawall Signed-off-by: Sage Weil
