Previously, pagers had no reference for being part of a node, only for
having a send right made for them. Hence we sometimes saw
use-after-free errors if the kernel did give up that send right,
typically while deleting files. Keep a weak reference as long as the
pager is referenced by a node.
* ext2fs/pager.c (pager_clear_user_data): Assert that 'pager' has been
NULLed.
(pager_dropweak): Drop the weak reference and NULL 'pager'.
(diskfs_get_filemap): Simplify. Acquire a weak reference.

unused info->i_high_size.

When cross-compiling, OTHERLIBS magically turns -lpthread into the path

On some systems, ext2fs.static would regularly hang at startup, as a
race condition meant it would process paging requests while remounting.
To fix this, libpager has been altered to allow inhibiting and resuming
its worker threads, and ext2fs uses this to inhibit paging while
remounting.

Previously, all users of libdiskfs implemented a node cache on their
own. Move the node cache from ext2fs into libdiskfs. We preserve the
previous API by marking all functions that we pull from ext2fs as
weak, so that users like tmpfs can still implement their own node
cache.

Previously, ext2fs used diskfs_node_refcnt_lock to serialize access to
the nodehash.
Use a separate lock to protect nodehash. Adjust the reference
counting accordingly. Every node in the nodehash carries a light
reference. When we are asked to give up that light reference, we
reacquire our lock momentarily to check whether someone else
reacquired a reference through the nodehash.
* ext2fs/inode.c (nodecache_lock): New lock.

Adjust the reference counting accordingly.

The node cache uses a fixed number of buckets giving it a linear

Previously, libpager used an unbounded number of threads to receive
messages from the pager bucket. It used sequence barriers to execute
the requests to order requests to each object.
The sequence barriers are implemented in seqnos.c. A server function
uses _pager_wait_for_seqno to wait for its sequence number and
_pager_release_seqno to release it, or it uses _pager_update_seqno to
do both operations in one step.
These sequence barriers divide each server function in three parts: A,
B, and C. A_i happens "before" the sequence barrier i, B_i happens
"in order", C_i happens "after" the sequence barrier. This partial
order < has the following properties:
* This order is *per object*. Requests to different objects are not
ordered.
* A_i < B_i, B_i < C_i (due to the structure of the code)
* B_i < B_{i+1} (this is due to the sequence barriers)
* Note that only the B parts are ordered by the sequence numbers, we
are free to execute C_i and C_{i+1} in any possible order. The same
argument applies to the A parts.
The sequence barriers are implemented using a very simple ticket
algorithm. Every request, even the invalid ones, is processed by a
thread, and waits until the ticket count reaches its seqno, does some
work in-order, then increments the ticket and awakes all threads that
have piled up up to this moment. All of them except one will then
discover that it's not their turn yet and go to sleep again.
Creating one thread per request has proven to be problematic as
memory_object requests often arrive in large batches.
This patch does two things:
* Use a single thread to receive messages from the port bucket. All
incoming request are put into a queue.
* Use a fixed-number of threads (though even one is actually enough)
to execute the the server functions. If multiple threads are used,
a work-delegation mechanism ensures that the per object order < is
preserved.
For reference, I used the following command to create workloads that
highlight the problem this patch is addressing:
% settrans t .../ext2fs --sync=30 /dev/sd2s1
...
% /usr/bin/time zsh -c 'for ((i=0; i < 1500; i++)); do

Previously, the superblock was mmaped and a pointer stored in sblock
by map_hypermetadata. This memory is backed by our disk pager.
This is rather unfortunate, as this means that whenever we read a
value from that location, we might generate a request our disk pager.
This amplifies the so-called thread-storm problem.
Rather than relying on a mmaped region of memory, just use the data
loaded by get_hypermetadata.

(mapped_sblock): New variable.

ext2fs has two kinds of pagers. One for the files, one for the disk.
Previously, both were in the same port bucket.
If a request for a file pager arrives, it most likely touches some
metadata (like the superblock). This is in turn backed by the disk
pager, so another request is generated for the disk pager.
Seperate all pagers clearly by using two port buckets. This will
enable us to use a single thread per port bucket in the future.
* ext2fs/pager.c (pager_bucket): Rename to...

Previously, inum was of type int, whereas dino_ref expects ino_t. On
Hurd/x86 the former is 32 bit wide, the latter 64. If dino_ref is
inlined, this does not seem to pose a problem, but if ext2fs is
compiled with -O0, this most likely results in an invalid memory access.
* ext2fs/ialloc.c (ext2_alloc_inode): Use type ino_t for inum.
