Modified files:
sys/dev : diskmap.c
Log message:
Favor vn_close() in the error path of diskmapioctl() since side-effects
caused by calling vn_open() with write permissions must be reverted.
Otherwise, the vfs subsystem could panic while releasing the last vnode
reference if the writecount is still positive.
