It\u0027s unclear\nwhether the underbarred ones assume that preemtion is disabled on\nentry as some callers don\u0027t do that.\n\nThis patch unifies diskstats access by implementing disk_stat_lock()\nand disk_stat_unlock() which take care of both RCU (for partition\naccess) and preemption (for per-cpu counter access).  diskstats access\nshould always be enclosed between the two functions.  As such, there\u0027s\nno need for the versions which disables preemption.  They\u0027re removed\nand double underbars ones are renamed to drop the underbars.  As an\nextra argument is added, there\u0027s no danger of using the old version\nunconverted.\n\ndisk_stat_lock() uses get_cpu() and returns the cpu index and all\ndiskstat functions which access per-cpu counters now has @cpu\nargument to help RT.\n\nThis change adds RCU or preemption operations at some places but also\ncollapses several preemption ops into one at others.

      "message": "[PATCH] md: remove personality numbering from md\n\nmd supports multiple different RAID level, each being implemented by a\n\u0027personality\u0027 (which is often in a separate module).\n\nThese personalities have fairly artificial \u0027numbers\u0027.  The numbers\nare use to:\n 1- provide an index into an array where the various personalities\n    are recorded\n 2- identify the module (via an alias) which implements are particular\n    personality.\n\nNeither of these uses really justify the existence of personality numbers.\nThe array can be replaced by a linked list which is searched (array lookup\nonly happens very rarely).  Module identification can be done using an alias\nbased on level rather than \u0027personality\u0027 number.\n\nThe current \u0027raid5\u0027 modules support two level (4 and 5) but only one\npersonality.  This slight awkwardness (which was handled in the mapping from\nlevel to personality) can be better handled by allowing raid5 to register 2\npersonalities.\n\nWith this change in place, the core md module does not need to have an\nexhaustive list of all possible personalities, so other personalities can be\nadded independently.\n\nThis patch also moves the check for chunksize being non-zero into the -\u003erun\nroutines for the personalities that need it, rather than having it in core-md.\n This has a side effect of allowing \u0027faulty\u0027 and \u0027linear\u0027 not to have a\nchunk-size set.\n\nSigned-off-by: Neil Brown \u003cneilb@suse.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"
