This will aid maintenance activites on the 5-stable branch. s/vfs_mount/vfs_omount/ s/vfs_nmount/vfs_mount/ Name our filesystems mount function consistently. Eliminate the namiedata argument to both vfs_mount and vfs_omount. It was originally there to save stack space. A few places abused it to get hold of some credentials to pass around. Effectively it is unused. Reorganize the root filesystem selection code. Make VFS_ROOT() and vflush() take a thread argument. 2004-07-12T08:14:09Z Alfred Perlstein alfred@FreeBSD.org 2004-07-12T08:14:09Z urn:sha1:f257b7a54b4fe77840cf694314bdc401e00c31a1 This is to allow filesystems to decide based on the passed thread which vnode to return. Several filesystems used curthread, they now use the passed thread.

It's unclear why these checks were removed in null_subr.c 1.35, but they are definitely necessary. Without the checks, trying to unmount a nullfs mount will erroneously return EBUSY, and forcibly unmounting with -f will cause a panic. - Bump LOG2_SIZEVNODE up to 8, since vnodes are >256 bytes now. The old value (7) didn't cause any problems, but made the hash algorithm suboptimal. These changes fix nullfs enough that a parallel buildworld succeeds.
