This commit was manufactured to restore the state of the 7.0-RELEASE image. Add information about the implications of using mmap(2) instead of sbrk(2). 2007-06-15T22:32:33Z Jason Evans jasone@FreeBSD.org 2007-06-15T22:32:33Z urn:sha1:0061e03d7fa2c712abf1fd3e267899f614f4598c Submitted by: bmah, jhb Update the IMPLEMENTATION NOTES section to reflect recent malloc 2007-03-28T04:34:19Z Jason Evans jasone@FreeBSD.org 2007-03-28T04:34:19Z urn:sha1:0a19939042534ba505aef7418a97fc9420491268 enhancements.

Reduce the chunk size from 16 MB to 2 MB. Since chunks are now carved up using an address-ordered first best fit policy, VM map fragmentation is much less likely, which makes smaller chunks not as much of a risk. This reduces the virtual memory size of most applications. Remove redzones, since program buffer overruns are no longer as likely to corrupt malloc data structures. Remove the C MALLOC_OPTIONS flag, and add H and S. Expand contractions. 2006-02-01T14:33:14Z Joel Dahl joel@FreeBSD.org 2006-02-01T14:33:14Z urn:sha1:fbf9b468d53247972564d3f3ec52b213156a3e94 Replace malloc(), calloc(), posix_memalign(), realloc(), and free() with 2006-01-13T18:38:56Z Jason Evans jasone@FreeBSD.org 2006-01-13T18:38:56Z urn:sha1:24b6d11c346ec90729405e7de40276af50e02aa7 a scalable concurrent allocator implementation.
