Justin Lebar e8eb0d970a Bug 903420 - Two fixes to jemalloc's memory reporters. r=glandium ... 1) We were counting "dirty" pages in "waste", when we shouldn't have been. This was causing the assertion at the end of jemalloc_stats() which checks that mapped memory is greater than committed memory to fail. 2) jemalloc_stats used stats_chunks.curchunks to measure the number of mapped pages. This was problematic for two reasons. a) stats_chunks.curchunks was not locked when it was modified in chunk_{de}alloc(), so its value could be garbage. b) Even if it had been locked properly, it was possible for an allocation to occur during a call to jemalloc_stats which would cause the measured amount of allocated memory to exceed the measured amount of mapped memory, tripping the assertion we tripped in (1). We fixed these issues by deleting stats_chunks entirely, and by introducing huge_mapped, which measures the amount of memory mapped by huge allocations (and is properly protected by huge_mtx). We now measure the amount of mapped memory by adding huge_mapped and each arena's mapped memory, and we do this in such a way that even if an allocation occurs during our call to jemalloc_stats, we'll still get a consistent result (where mapped >= committed).		2013-08-15 11:15:04 -07:00
