Modified files:
sys/fs/devfs devfs_vnops.c
sys/fs/fifofs fifo_vnops.c
sys/kern uipc_usrreq.c vfs_vnops.c
sys/vm vnode_pager.c
Log:
When we do open, we should lock the vnode exclusively. This fixes few races:
- fifo race, where two threads assign v_fifoinfo,
- v_writecount modifications,
- v_object modifications,
- and probably more...
