- Replace v_flag with v_iflag and v_vflag2002-08-04T10:29:36ZJeff Robersonjeff@FreeBSD.org2002-08-04T10:29:36Zurn:sha1:e6e370a7fe930e04cec38bcc2e06be127ed7ee02
- v_vflag is protected by the vnode lock and is used when synchronization
with VOP calls is needed.
- v_iflag is protected by interlock and is used for dealing with vnode
management issues. These flags include X/O LOCK, FREE, DOOMED, etc.
- All accesses to v_iflag and v_vflag have either been locked or marked with
mp_fixme's.
- Many ASSERT_VOP_LOCKED calls have been added where the locking was not
clear.
- Many functions in vfs_subr.c were restructured to provide for stronger
locking.

Back out my lats commit of locking down a socket, it conflicts with hsu's work.2002-05-31T11:52:35ZSeigo Tanimuratanimura@FreeBSD.org2002-05-31T11:52:35Zurn:sha1:4cc20ab1f0f3d1126126327aa298ab88c974c53d

Lock down a socket, milestone 1.2002-05-20T05:41:09ZSeigo Tanimuratanimura@FreeBSD.org2002-05-20T05:41:09Zurn:sha1:243917fe3b5e36464ab72473e872da9acd44aa1c
o Add a mutex (sb_mtx) to struct sockbuf. This protects the data in a
socket buffer. The mutex in the receive buffer also protects the data
in struct socket.
o Determine the lock strategy for each members in struct socket.
o Lock down the following members:
- so_count
- so_options
- so_linger
- so_state
o Remove *_locked() socket APIs. Make the following socket APIs
touching the members above now require a locked socket:
- sodisconnect()
- soisconnected()
- soisconnecting()
- soisdisconnected()
- soisdisconnecting()
- sofree()
- soref()
- sorele()
- sorwakeup()
- sotryfree()
- sowakeup()
- sowwakeup()
