Modified files:
sys/fs/pseudofs pseudofs_vnops.c
Log:
Commit a work-around for a more general bug involving process state:
check whether p_ucred is NULL or not in pfs_getattr() before
dereferencing the credential, and return ENOENT if there wasn't one.
This is a symptom of a larger problem, wherein pfind() can return
references to incompletely initialized processes, and we instead ought
to not return them, or check the process state before acting on the
process.
