yamt 5d63916ff3 do minimal locking to make assertions like KASSERT(VOP_ISLOCKED(vp)) happy. 2010-12-17 22:03:00 +00:00
hannken c2de422c87 LK_INTERLOCK is no longer a valid flag for VOP_LOCK(). 2010-07-02 07:56:46 +00:00
dsl 82357f6d42 ANSIfy another 1261 function definitions. 
The only ones left in sys are beyond by sed script!
(or in sys/dist or sys/external)
Mostly they have function pointer parameters.

ad 1997a1e1f4 Remove VOP_LEASE. Discussed on tech-kern. 2008-01-25 14:32:11 +00:00
ad 4a780c9ae2 Merge vmlocking2 to head. 2008-01-02 11:48:20 +00:00
ad 7dad9f7391 Merge from vmlocking: 
- Split vnode::v_flag into three fields, depending on field locking.
- simple_lock -> kmutex in a few places.
- Fix some simple locking problems.

ad a0d1fd8d0c It's not a good idea for device drivers to modify b_flags, as they don't 
need to understand the locking around that field. Instead of setting
B_ERROR, set b_error instead. b_error is 'owned' by whoever completes
the I/O request.

pooka 4013808f45 Teach deadfs about vm object locking for getpages. This avoids 
errors resulting from situations where we take a page fault for a
vnode which has been converted a deadfs vnode.

chs c398ae9734 a smorgasbord of improvements to vnode locking and path lookup: 
- LOCKPARENT is no longer relevant for lookup(), relookup() or VOP_LOOKUP().
   these now always return the parent vnode locked.  namei() works as before.
   lookup() and various other paths no longer acquire vnode locks in the
   wrong order via vrele().  fixes PR 32535.
   as a nice side effect, path lookup is also up to 25% faster.
 - the above allows us to get rid of PDIRUNLOCK.
 - also get rid of WANTPARENT (just use LOCKPARENT and unlock it).
 - remove an assumption in layer_node_find() that all file systems implement
   a recursive VOP_LOCK() (unionfs doesn't).
 - require that all file systems supply vfs_vptofh and vfs_fhtovp routines.
   fill in eopnotsupp() for file systems that don't support being exported
   and remove the checks for NULL.  (layerfs calls these without checking.)
 - in union_lookup1(), don't change refcounts in the ISDOTDOT case, just
   adjust which vnode is locked.  fixes PR 33374.
 - apply fixes for ufs_rename() from ufs_vnops.c rev. 1.61 to ext2fs_rename().

xtraeme af97f2e875 Remove __P() 2005-08-30 20:08:01 +00:00
jrf fc97fd571a First pass for some caddr_t removal and changes to get rid of it where we 
no longer use and/or need it

	- removed casts from unionfs, deadfs and fdesc
	  (there are more to hunt down still)
	- changed vfs_quotactl args argumet from caddr_t to void *
	- changed vfs_quotactl structures/callers to reflect the api change

Compiled fine and ran for about a day. Approved/reviewed by
christos@netbsd.org and gimpy@netbsd.org.

hannken 3db4e2acd8 Make VOP_STRATEGY(bp) a real VOP as discussed on tech-kern. 
VOP_STRATEGY(bp) is replaced by one of two new functions:

- VOP_STRATEGY(vp, bp)  Call the strategy routine of vp for bp.
- DEV_STRATEGY(bp)      Call the d_strategy routine of bp->b_dev for bp.

DEV_STRATEGY(bp) is used only for block-to-block device situations.
