Fix the shrinking case of huge_ralloc_no_move_similar() to purge the correct number of pages, at the correct offset. This regression was introduced by 8d6a3e8321a7767cb2ca0930b85d5d488a8cc659 (Implement dynamic per arena control over dirty page purging.). Fix huge_ralloc_no_move_shrink() to purge the correct number of pages. This bug was introduced by 9673983443a0782d975fbcb5d8457cfd411b8b56 (Purge/zero sub-chunk huge allocations as necessary.).
jemalloc is a general purpose malloc(3) implementation that emphasizes fragmentation avoidance and scalable concurrency support. jemalloc first came into use as the FreeBSD libc allocator in 2005, and since then it has found its way into numerous applications that rely on its predictable behavior. In 2010 jemalloc development efforts broadened to include developer support features such as heap profiling, Valgrind integration, and extensive monitoring/tuning hooks. Modern jemalloc releases continue to be integrated back into FreeBSD, and therefore versatility remains critical. Ongoing development efforts trend toward making jemalloc among the best allocators for a broad range of demanding applications, and eliminating/mitigating weaknesses that have practical repercussions for real world applications. The COPYING file contains copyright and licensing information. The INSTALL file contains information on how to configure, build, and install jemalloc. The ChangeLog file contains a brief summary of changes for each release. URL: http://www.canonware.com/jemalloc/
