Ben Gras	f08f2bd88c	new free_contig() and changes to make drivers use it; so now we ... have malloc/free, alloc_contig/free_contig and mmap/munmap nicely paired up. memory uses malloc/free instead of mmap/munmap as it doesn't have to be contiguous for the ramdisks (and it might help if it doesn't!).	2010-02-10 13:56:26 +00:00
David van Moolenbroek	92ae5c81ae	Filter driver updates: ... - optionally vectorize I/O requests to work around hardware bugs - extend default buffer size to cover MFS's default maximum request size - use mmap directly, rather than alloc_contig - add 'nil' checksum type for comparison with layout - minor style corrections	2009-12-21 23:30:01 +00:00
