sommerfe 75fb6d661f Include some comments with more details on the VOP_LOOKUP locking protocol 1999-03-22 16:57:37 +00:00
wrstuden 0078fc50dc Modify VOP_CLOSE vnode op to always take a locked vnode. Change vn_close 
to pass down a locked node. Modify union_copyup() to call VOP_CLOSE
locked nodes.

Also fix a bug in union_copyup() where a lock on the lower vnode would
only be released if VOP_OPEN didn't fail.

kleink c77a008cc2 Replace the `waitfor' argument to the fsync vnode operator with a `flags' 
argument.

mycroft 2bc736661a Implement poll(2). 1996-09-07 12:40:22 +00:00
mycroft 261382c331 Change VOP_UPDATE() semantics: 
* Make 2nd and 3rd args timespecs, not timevals.
* Consistently pass a Boolean as the 4th arg (except in LFS).
Also, fix ffs_update() and lfs_update() to actually change the nsec fields.

mycroft 53fccab940 Fix vop_link, vop_symlink, and vop_remove semantics in several ways: 
* Change the argument names to vop_link so they actually make sense.
* Implement vop_link and vop_symlink for all file systems, so they do proper
  cleanup.
* Require the file system to decide whether or not linking and unlinking of
  directories is allowed, and disable it for all current file systems.
