'RELENG_5_3_0_RELEASE'.

This commit was manufactured to restore the state of the 5.3-RELEASE image.

Rename suser_cred()'s PRISON_ROOT flag to SUSER_ALLOWJAIL. This is

2004-07-26T07:24:04+00:00

somewhat clearer, but more importantly allows for a consistent naming
scheme for suser_cred flags.

The old name is still defined, but will be removed in a few days (unless I
hear any complaints...)

In devfs_allocv(), rather than assigning 'td = curthread', assert that

2004-07-22T17:03:14+00:00

the caller passes in a td that is curthread, and consistently pass 'td'
into vget().  Remove some bogus logic that passed in td or curthread
conditional on td being non-NULL, which seems redundant in the face of
the earlier assignment of td to curthread if td is NULL.

In devfs_symlink(), cache the passed thread in 'td' so we don't have
to keep retrieving it from the 'ap' structure, and assert that td is
curthread (since we dereference it to get thread-local td_ucred).  Use
'td' in preference to curthread for later lockmgr calls, since they are
equal.

Second half of the dev_t cleanup.

The big lines are:
	NODEV -> NULL
	NOUDEV -> NODEV
	udev_t -> dev_t
	udev2dev() -> findcdev()

Various minor adjustments including handling of userland access to kernel
space struct cdev etc.

Do the dreaded s/dev_t/struct cdev */

Bump __FreeBSD_version accordingly.

Report the correct length for symlink entries.

Improve on POLA by populating DEVFS before doing devfs(8) rule ioctls.

Remember to check the DE_WHITEOUT flag in the case where a cloned

2003-10-20T15:08:10+00:00

device is hidden by a devfs(8) rule.

When a driver successfully created a device on demand, we can directly

2003-10-20T07:04:09+00:00

pick up the DEVFS inode number from the dev_t and find our directory
entry from that, we don't need to scan the directory to find it.

This also solves an issue with on-demand devices in subdirectories.

Remove unused variable.
