jeff 2005-03-29 10:07:15 UTC FreeBSD src repository Modified files: sys/kern vfs_lookup.c Log: - Set cn_lkflags to LK_SHARED in the LOOKUP_SHARED case so that we only acquire shared locks on intermediate directories. - For the LASTCN, we may have to LK_UPGRADE the parent directory before we lookup the last component. - Acquire VFS_ROOT and dp locks based on the cn_lkflag.
