alc 2010-10-15 05:42:35 UTC FreeBSD src repository Modified files: (Branch: RELENG_8) sys/kern vfs_bio.c Log: SVN rev 213890 on 2010-10-15 05:42:35Z by alc MFC r209605 Improve bufdone_finish()'s handling of the bogus page. Specifically, if one or more mappings to the bogus page must be replaced, call pmap_qenter() just once. Previously, pmap_qenter() was called for each mapping to the bogus page. MFC r209902 Change the implementation of vm_hold_free_pages() so that it performs at most one call to pmap_qremove(), and thus one TLB shootdown, instead of one call and TLB shootdown per page. Simplify the interface to vm_hold_free_pages(). Revision Changes Path 1.568.2.7 +22 -30 src/sys/kern/vfs_bio.c
