      "message": "percpu_counters(): use cpu notifiers\n\nper-cpu counters presently must iterate over all possible CPUs in the\nexhaustive percpu_counter_sum().\n\nBut it can be much better to only iterate over the presently-online CPUs.  To\ndo this, we must arrange for an offlined CPU\u0027s count to be spilled into the\ncounter\u0027s central count.\n\nWe can do this for all percpu_counters in the machine by linking them into a\nsingle global list and walking that list at CPU_DEAD time.\n\n(I hope.  Might have race windows in which the percpu_counter_sum() count is\ninaccurate?)\n\nCc: Gautham R Shenoy \u003cego@in.ibm.com\u003e\nCc: Oleg Nesterov \u003coleg@tv-sign.ru\u003e\nCc: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

      "message": "[PATCH] percpu counter data type changes to suppport more than 2**31 ext3 free blocks counter\n\nThe percpu counter data type are changed in this set of patches to support\nmore users like ext3 who need more than 32 bit to store the free blocks\ntotal in the filesystem.\n\n- Generic perpcu counters data type changes.  The size of the global counter\n  and local counter were explictly specified using s64 and s32.  The global\n  counter is changed from long to s64, while the local counter is changed from\n  long to s32, so we could avoid doing 64 bit update in most cases.\n\n- Users of the percpu counters are updated to make use of the new\n  percpu_counter_init() routine now taking an additional parameter to allow\n  users to pass the initial value of the global counter.\n\nSigned-off-by: Mingming Cao \u003ccmm@us.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"
