| H A D | msdosfs_vfsops.c | diff 58706 Mon Mar 27 19:29:33 MST 2000 dillon Commit the buffer cache cleanup patch to 4.x and 5.x. This patch fixes a fragmentation problem due to geteblk() reserving too much space for the buffer and imposes a larger granularity (16K) on KVA reservations for the buffer cache to avoid fragmentation issues. The buffer cache size calculations have been redone to simplify them (fewer defines, better comments, less chance of running out of KVA). The geteblk() fix solves a performance problem that DG was able reproduce. This patch does not completely fix the KVA fragmentation problems, but it goes a long way Mostly Reviewed by: bde and others Approved by: jkh |
