freebsd with flexible iflib nic queues
a489f7614b
Removed call to vm_object_collapse(), which can block. This was being called without the pageout code holding any sort of reference on the vm_object or vm_page_t structures being manipulated. Since this code can block, it was possible for other kernel code to shred the state the pageout code was assuming remained intact. Fixed potential blocking condition in vm_pageout_page_free() ( which could cause a deadlock in a low-memory situation ). Currently there is a hack in-place to deal with clean filesystem meta-data polluting the inactive page queue. John doesn't like the hack, and neither do I. Revamped and commented a portion of the pageout loop. Added protection against potential memory deadlocks with OBJT_VNODE when using VOP_ISLOCKED(). The problem is that vp->v_data can be NULL which causes VOP_ISLOCKED() to return a less informed answer. remove vm_pager_sync() -- none of the pagers use it any more ( the old swapper used to. The new one does not ). |

UPDATING |
This is the top level of the FreeBSD source directory. This file was last revised on: $Id: README,v 1.13 1998/09/13 09:38:34 markm Exp $ For copyright information, please see the file COPYRIGHT in this directory (additional copyright information also exists for some sources in this tree - please see the specific source directories for more information). The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree, the most commonly used one being ``world'', which rebuilds and installs everything in the FreeBSD system from the source tree except the kernel and the contents of /etc. Please see the top of the Makefile in this directory for more information on the standard build targets and compile-time flags. Building a kernel with config(8) is a somewhat more involved process, documentation for which can be found at: http://www.freebsd.org/handbook/kernelconfig.html And in the config(8) man page. The sample kernel configuration files reside in the sys/i386/conf sub-directory (assuming that you've installed the kernel sources), the file named GENERIC being the one used to build your initial installation kernel. The file LINT contains entries for all possible devices, not just those commonly used, and is meant more as a general reference than an actual kernel configuration file (a kernel built from it wouldn't even run).
