Fail namei immediately if searchdir is unlinked / has been rmdir'd.
Do this by checking if v_size == 0. Should fix PR 44658 (and PR 32661).
why is this necessary? can't we just let VOP_LOOKUP fail
.

is extattr_namespace_access really necessary?
uid-based priviledge check in userland is often a mistake.
For now it duplicates the same simple access check as in kernel:
system attributes are restricted to root

Here is the updated patch after your changes:
http://www.netbsd.org/~rmind/uvm_anon_freelst2.diff
As you noted, uvm_anfree() can temporarily release the amap lock - that
can happen in amap_copy
the filesystem.
This avoids deadlocks in the following situations:
1) when memory is low: ioflush waits the fileystem, the fielsystem waits
for memory
can you explain how it is a problem?

2) when the filesystem does not respond (e.g.: network outage ona

in this way. please revert.

As I understand, one way to free memory is to flush vnode

as i told you a few times, ioflush is not a thread to free memory.
pagedaemon is.
Sure ioflush do not directly free memory, but vnodes' dirty page use
memory, don't they? If ioflush stops working, is pageadaemon able to
pageout

pagedaemon flushes dirty pages by itself, yes.

if it trapped forever, it's a bug and should be fixed. my point was
that your change didn't fix the bug. blocking ioflush is merely a symptom.
The problem with userland filesystems is that we may have little control
as theses may

hi,
is a nointr pool safe for this pmap?
iirc x86 pmap allocates pv entries from kmem_map to avoid this kind of
recursion.
