Things noticable from users' perspective : * dropped klibc from the package : now an external dependency. Those interested in building the tools with klcc will want to download klibc from http://www.kernel.org/pub/linux/libs/klibc/ or the nearest mirror. * optimization work in the multipath tool : shorter code paths and less memory utilisation * new "multipath -v2 -l $devmap" synthax to limit the scope of the list * new rr_min_io keyword in the config file * allow longer devmaps (256 to 1024 chars) * "multipath -F" will no longer flush maps with partitions attached Full ChangeLog for the release : * [libmultipath] rename find_[mp|hw] to find_[mp|hw]e and introduce a real find_mp(). * [priority] provison for recursive compilation of prio subdirs, in preparation of merging more signicant prioritizers. Stephan Bader, IBM * [libmultipath] add a netapp controler to the hwtable * [libmultipath] blacklist() not to discard sda[0-9]* when sda is blacklisted * [multipath] add a rr_min_io keyword in config file. Suggested by Igor Feoktistov, NetApp * [multipath] stop trying to avoid running in parallel * [multipath] bump up params size to 1024 * [multipathd] put prio callouts in to ramfs. Stephan Bader, IBM * [multipath] simplify multibus pgpolicy : no need to copy mp->paths into mp->pg->paths then free source : just copy the ptr and set source to NULL. * [multipath] sort PG by descending prio value in group_by_prio. Stephan Bader, IBM * [multipath] fix a bug in group_by_prio that lead to creation of multiple PG for a single prio value * [multipath] don't store multipaths in a vector anymore : free the "struct multipath" after usage. * [multipath] multiple optimizations in the exec plan * [multipath] allow "multipath -l -v2 [mapname|wwid]" * [build] rip off klibc and move to klcc, at last. Good job hpa. multipath-tools now depend on klibc > 1.0 to build with BUILD=klibc flag. * [multipath] never reload a map if no path is up in the computed new map * [multipath] don't flush maps with open count != 0 * [libmultipath] add "int *dm_get_opencount(char *map)" to devmapper.c * [multipath] plug leaks and optimize devinfo.c. From Edward Goggin, EMC * [multipath] fix the multipath.dev hotplug script to not do kpartx stuff in the same run as multipath stuff. * [multipath] fix the multipath.dev hotplug script to not do kpartx stuff in the same run as multipath stuff. Igor Feoktistov, NetApp, noted the devmap symlink was not yet present for kpartx to use. * [devmap_name] accept major:minor synthax * [libmultipath] add "char *dm_mapname(int maj, int min)", needed to fail paths from checker thread * [libmultipath] move dm_reinstate() in the lib, and add dm_fail_path() * [multipathd] mark failed path as failed upon DM event. This should fix the design bug noticed by Ramesh Caushik, Intel, where the daemon didn't run multipath when a path went down and up in between 2 checks. * [libmultipath] allow NULL as a pathvec in disassemble_map as is passed only for memory optimization * [libmultipath] add structs.c to store alloc_*() and free_*() * [libmultipath] move dmparser.[ch] to the lib. remove devinfo.[ch] dependency. * [build] fix compilation glitch with BUILD=klibc, flags to force use of local libs, remove the link dependency in klibc, try to guess kernel sources and build dirs. Stefan Bader, IBM * [libmultipath] find_hw matching logic to take str lengths in account. Noticed by Ramesh Caushik, Intel * [multipath] select_action matching logic to take str length in account. * [multipath] lookup mp alias name earlier (in coalesce) Edward Goggin, EMC, noticed we tried to use it before it was set up.
