206e9582ef Move lock.h and kern_lock.c to their rightful places, as in Lite2. Make 
the VM code use the new interface.

8c0a9bab00 Don't cast 64bit (off_t) file sizes to vm_offset_t (32bit on many 
architectures), truncate them intelligently instead.
The truncation is done centralized in vnode_pager.c.
This prevents from wrap-over effects when parts of large (>2^32 byte) files
are mmapped.
Don't allow to mmap above the numerical range of vm_offset_t.
This is considered a temporary solution until the vm system handles the
object sizes/offsets more cleanly.

700dee447e DTRT if vm_object_lookup() returns NULL. This may happen while an object is 
being created or destroyed.

fad978b853 a mutex on vnode_pager_sync avoids another race condition, only possible if sync were called again while we were sleeping. This should be the last of this nest of bugs. From mycroft. 1997-02-26 02:26:19 +00:00

75be8504f4 More good stuff from Charles: 
Eliminate a nasty race condition in vnode_pager_sync() by making
two passes.  First, find all of the objects to be cleaned and reference
them.  Second, traverse this list objects, cleaning them if there are
references other than us.

17b60fc6e9 In vnode_pager_sync(), we need to vm_object_deallocate() after cleaning 
pages.  Noticed by Thor Simon <tls@netbsd.org>, confirmed by
Charles Hannum <mycroft@netbsd.org>

127c6b54e7 Sigh. I initially had this exactly backwards: the object needs to be locked, the vnode does *not*. Avoids panic: locking against myself quickly reported by Charles. 1997-02-17 13:10:28 +00:00
tls
a507fda378 vnode_pager_sync bugs: A) must lock the object, not just the vnode. B) Don't remove the object from paging queues, because we'd have to put it back on one. The pagedaemon will eventually take care of this for us anyway. This was causing us to *lose track of pages completely* every time vnode_pager_sync() was called... sigh. Credit goes to mycroft for untangling this mess. 1997-02-17 06:22:52 +00:00
