sys/sys filedesc.h
sys/kern kern_descrip.c vfs_syscalls.c
Log:
MFC rev. 1.309 of sys/kern/kern_descrip.c,
rev. 1.438 of sys/kern/vfs_syscalls.c,
rev. 1.77 of sys/sys/filedesc.h:
Mark the filedescriptor table entries with VOP_OPEN being performed for them
as UF_OPENING. Disable closing of that entries. This should fix the crashes
caused by devfs_open() (and fifo_open()) dereferencing struct file * by
index, while the filedescriptor is closed by parallel thread.
