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. Overall, the\nperformance difference should be negligible as all involved ops are\nvery lightweight per-cpu ones.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nCc: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nSigned-off-by: Jens Axboe \u003cjens.axboe@oracle.com\u003e\n" }, { "commit": "e71bf0d0ee89e51b92776391c5634938236977d5", "tree": "9fc62352a40ad388deebdd8ed497cab926cf0470", "parents": [ "f331c0296f2a9fee0d396a70598b954062603015" ], "author": { "name": "Tejun Heo", "email": "tj@kernel.org", "time": "Wed Sep 03 09:03:02 2008 +0200" }, "committer": { "name": "Jens Axboe", "email": "jens.axboe@oracle.com", "time": "Thu Oct 09 08:56:06 2008 +0200" }, "message": "block: fix disk-\u003epart[] dereferencing race\n\ndisk-\u003epart[] is protected by its matching bdev\u0027s lock.
