userfs/src/sys/miscfs/puffs: puffs.h puffs_vfsops.c puffs_vnops.c
Log Message:
rework root vnode handling: instead of holding on to it always,
let it go if need be and re-get one in puffs_root(). This moves
some complexity into puffs_root() but takes it out of puffs_unmount(),
where it is harder to handle due to more volatility with states.
The userspace never gets to know about root vnode reclaim, it is
destroyed only at unmount.
following cases work now:
/> umount /puffs -> ok
/puffs> umount /puffs -> busy
/puffs> umount -f /puffs -> ok
/> pkill dtfs -> ok unmount
/puffs> pkill dtfs -> ok unmount
per discussion with *the* Bill!
