* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/sage/ceph-client: ceph: add missing spin_unlock at ceph_mdsc_build_path() ceph: fix SEEK_CUR, SEEK_SET regression crush: fix mapping calculation when force argument doesn't exist ceph: use i_ceph_lock instead of i_lock rbd: remove buggy rollback functionality rbd: return an error when an invalid header is read ceph: fix rasize reporting by ceph_show_options

crush: fix mapping calculation when force argument doesn't exist

2011-12-12T17:09:45Z

If the force argument isn't valid, we should continue calculating a mapping as if it weren't specified. Signed-off-by: Sage Weil

libceph: Allocate larger oid buffer in request msgs

2011-11-11T17:50:19Z

ceph_osd_request struct allocates a 40-byte buffer for object names. RBD image names can be up to 96 chars long (100 with the .rbd suffix), which results in the object name for the image being truncated, and a subsequent map failure. Increase the oid buffer in request messages, in order to avoid the truncation. Signed-off-by: Stratos Psomadakis Signed-off-by: Sage Weil

net: Add export.h for EXPORT_SYMBOL/THIS_MODULE to non-modules

2011-10-31T23:30:30Z

These files are non modular, but need to export symbols using the macros now living in export.h -- call out the include so that things won't break when we remove the implicit presence of module.h from everywhere. Signed-off-by: Paul Gortmaker

libceph: force resend of osd requests if we skip an osdmap

2011-10-25T23:10:17Z

If we skip over one or more map epochs, we need to resend all osd requests because it is possible they remapped to other servers and then back. Signed-off-by: Sage Weil

ceph: use kernel DNS resolver

2011-10-25T23:10:16Z

Change ceph_parse_ips to take either names given as IP addresses or standard hostnames (e.g. localhost). The DNS lookup is done using the dns_resolver facility similar to its use in AFS, NFS, and CIFS. This patch defines CONFIG_CEPH_LIB_USE_DNS_RESOLVER that controls if this feature is on or off.

ceph: fix ceph_monc_init memory leak

2011-10-25T23:10:16Z

failure clean up does not consider ceph_auth_init. Signed-off-by: Noah Watkins Signed-off-by: Sage Weil

libceph: warn on msg allocation failures

2011-10-25T23:10:16Z

Any non-masked msg allocation failure should generate a warning and stack trace to the console. All of these need to eventually be replaced by safe preallocation or msgpools. Signed-off-by: Sage Weil

libceph: don't complain on msgpool alloc failures

2011-10-25T23:10:15Z

The pool allocation failures are masked by the pool; there is no need to spam the console about them. (That's the whole point of having the pool in the first place.) Mark msg allocations whose failure is safely handled as such. Signed-off-by: Sage Weil
