bp 2000/09/17 00:26:42 PDT Modified files: sys/kern vfs_cache.c vfs_lookup.c sys/sys namei.h sys/ufs/ufs ufs_lookup.c Log: Add new flag PDIRUNLOCK to the component.cn_flags which should be set by filesystem lookup() routine if it unlocks parent directory. This flag should be carefully tracked by filesystems if they want to work properly with nullfs and other stacked filesystems. VFS takes advantage of this flag to perform symantically correct usage of vrele() instead of vput() if parent directory already unlocked. If filesystem fails to track this flag then previous codepath in VFS left unchanged. Convert UFS code to set PDIRUNLOCK flag if necessary. Other filesystmes will be changed after some period of testing.
