* If we specify: mount -u (update), without specifying anrodrigc2006-02-251-11/+7
| | | | | | | | | | | | additional -r (read-only) flag or or -w (read-write) flag, then assume we want, mount -u -w. When doing a mount update, this will implicitly pass a "noro" mount option down to the VFS layer. vfs_mergeopts() in vfs_mount.c will then remove the "ro" mount option if it exists in the mount options for a mounted file system. This means that "mount -u" works the same as "mount -u -w" and will convert a read-only mount to read-write.

| | | | | | | | - mount(8) now calls the nmount(2) system call directly, not mount(2) - specifying a filesystem type with -t will not automatically invoke an external /sbin/mount_XXXX program....this only happens for certain file system types. For all other file system types, nmount(2) is called directly.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Reorder the events in exit(2) slightly so that we trigger the S_EXIT stop event earlier. After we have signalled that, we set P_WEXIT and then wait for any processes with a hold on the vmspace via PHOLD to release it. PHOLD now KASSERT()'s that P_WEXIT is clear when it is invoked, and PRELE now does a wakeup if P_WEXIT is set and p_lock drops to zero. - Change proc_rwmem() to require that the processing read from has its vmspace held via PHOLD by the caller and get rid of all the junk to screw around with the vmspace reference count as we no longer need it. - In ptrace() and pseudofs(), treat a process with P_WEXIT set as if it doesn't exist. - Only do one PHOLD in kern_ptrace() now, and do it earlier so it covers FIX_SSTEP() (since on alpha at least this can end up calling proc_rwmem() to clear an earlier single-step simualted via a breakpoint). We only do one to avoid races. Also, by making the EINVAL error for unknown requests be part of the default: case in the switch, the various switch cases can now just break out to return which removes a _lot_ of duplicated PRELE and proc unlocks, etc. Also, it fixes at least one bug where a LWP ptrace command could return EINVAL with the proc lock still held. - Changed the locking for ptrace_single_step(), ptrace_set_pc(), and ptrace_clear_single_step() to always be called with the proc lock held (it was a mixed bag previously). Alpha and arm have to drop the lock while the mess around with breakpoints, but other archs avoid extra lock release/acquires in ptrace(). I did have to fix a couple of other consumers in kern_kse and a few other places to hold the proc lock and PHOLD. Tested by: ps (1 mostly, but some bits of 2-4 as well) MFC after: 1 week

This allows a lot of places that were calling pfind() again right after pfs_visible() to not have to do that and avoids races since we don't drop the proc lock just to turn around and lock it again. This will become more important with future changes to fix races between procfs/ptrace and exit(2). Also, removed a duplicate pfs_visible() call in pfs_getextattr().
