linux.git/net/ceph, branch v3.2-rc1 Linux kernel source tree net: Add export.h for EXPORT_SYMBOL/THIS_MODULE to non-modules 2011-10-31T23:30:30+00:00 Paul Gortmaker paul.gortmaker@windriver.com 2011-07-15T15:47:34+00:00 bc3b2d7fb9b014d75ebb79ba371a763dbab5e8cf 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.

libceph: force resend of osd requests if we skip an osdmap 2011-10-25T23:10:17+00:00 Sage Weil sage@newdream.net 2011-10-14T20:33:55+00:00 38d6453ca39ecce442628a93e1bb46d70d547512 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.

ceph: use kernel DNS resolver 2011-10-25T23:10:16+00:00 Noah Watkins noahwatkins@gmail.com 2011-09-23T18:48:42+00:00 ee3b56f265cafb28c9a1b58faed4f1dbdf51af86 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.
