hannken 7a5be5a9ff - Add flag L_COWINPROGRESS to struct lwp to avoid recursion when ... doing copy-on-write. - Change VFS_SNAPSHOT() to return the snapshot vnode locked. - Make the IO path for copy-on-write and snapshot-read more lightweight. Avoids deadlocks where vn_rdwr(...READ...) has a shared lock and needs to copy-on-write. Avoids deadlocks/panics where to clean pages the copy-on-write needs to allocate pages for its VOP_PUTPAGES(). L_COWINPROGRESS part approved by: Jason R. Thorpe <thorpej@netbsd.org>		2004-06-20 18:55:58 +00:00
