First, function gfs2_ail_flush_reqd checks the SDF_FORCE_AIL_FLUSH flag
to determine if an AIL flush should be forced in low-memory situations.
However, it also immediately clears the flag, and when called repeatedly
as in function gfs2_logd, the flag will be lost.  Fix that by pulling
the SDF_FORCE_AIL_FLUSH flag check out of gfs2_ail_flush_reqd.

Second, function gfs2_writepages sets the SDF_FORCE_AIL_FLUSH flag
whether or not enough pages were written.  If enough pages could be
written, flushing the AIL is unnecessary, though.

Third, gfs2_writepages doesn't wake up logd after setting the
SDF_FORCE_AIL_FLUSH flag, so it can take a long time for logd to react.
It would be preferable to wake up logd, but that hurts the performance
of some workloads and we don't quite understand why so far, so don't
wake up logd so far.

Consider the following case:
1. A glock is held in shared mode.
2. A process requests the glock in exclusive mode (rename).
3. Before the lock is granted, more processes (read / ls) request the
   glock in shared mode again.
4. gfs2 sends a request to dlm for the lock in exclusive mode because
   that holder is at the head of the queue.
5. Somehow the dlm request gets canceled, so dlm sends us back a
   response with state == LM_ST_SHARED and LM_OUT_CANCELED.  So at that
   point, the glock is still held in shared mode.
6. finish_xmote gets called to process the response from dlm. It detects
   that the glock is not in the requested mode and no demote is in
   progress, so it moves the canceled holder to the tail of the queue
   and finds the new holder at the head of the queue.  That holder is
   requesting the glock in shared mode.
7. finish_xmote calls do_xmote to transition the glock into shared mode,
   but the glock is already in shared mode and so do_xmote complains
   about that with:
	GLOCK_BUG_ON(gl, gl->gl_state == gl->gl_target);

Instead, in finish_xmote, after moving the canceled holder to the tail
of the queue, check if any new holders can be granted.  Only call
do_xmote to repeat the dlm request if the holder at the head of the
queue is requesting the glock in a mode that is incompatible with the
mode the glock is currently held in.

Revert the rest of commit 220cca2a ("GFS2: Change truncate page
allocation to be GFP_NOFS"):

In gfs2_unstuff_dinode(), there is no need to carry out the page cache
allocation under GFP_NOFS because inodes on the "regular" filesystem are
never un-inlined under memory pressure, so switch back from
find_or_create_page() to grab_cache_page() here as well.

Inodes on the "metadata" filesystem can theoretically be un-inlined
under memory pressure, but any page cache allocations in that context
would happen in GFP_NOFS context because those inodes have
inode->i_mapping->gfp_mask set to GFP_NOFS (see the previous patch).
Signed-off-by: Andreas Gruenbacher <agruenba@redhat.com>

Set mapping->gfp mask to GFP_NOFS for all metadata inodes so that
allocating pages in the address space of those inodes won't call back
into the filesystem.  This allows to switch back from
find_or_create_page() to grab_cache_page() in two places.

Starting with patch 2cb1e089, gfs2 started using the new function
filemap_splice_read rather than the old (and subsequently deleted)
function generic_file_splice_read.

filemap_splice_read works by taking references to a number of folios in
the page cache and splicing those folios into a pipe.  The folios are
then read from the pipe and the folio references are dropped.  This can
take an arbitrary amount of time.  We cannot allow that in gfs2 because
those folio references will pin the inode glock to the node and prevent
it from being demoted, which can lead to cluster-wide deadlocks.

Instead, use copy_splice_read.

(In addition, the old generic_file_splice_read called into ->read_iter,
which called gfs2_file_read_iter, which took the inode glock during the
operation.  The new filemap_splice_read interface does not take the
inode glock anymore.  This is fixable, but it still wouldn't prevent
cluster-wide deadlocks.)

Function gfs2_trans_add_meta() checks for the SDF_FROZEN flag to make
sure that no buffers are added to a transaction while the filesystem is
frozen.  With the recent freeze/thaw rework, the SDF_FROZEN flag is
cleared after thaw_super() is called, which is sufficient for
serializing freeze/thaw.

However, other filesystem operations started after thaw_super() may now
be calling gfs2_trans_add_meta() before the SDF_FROZEN flag is cleared,
which will trigger the SDF_FROZEN check in gfs2_trans_add_meta().  Fix
that by checking the s_writers.frozen state instead.

In addition, make sure not to call gfs2_assert_withdraw() with the
sd_log_lock spin lock held.  Check for a withdrawn filesystem before
checking for a frozen filesystem, and don't pin/add buffers to the
current transaction in case of a failure in either case.

While at it, make SMT detection more robust as some guests - depending
on how and what CPUID leafs their report - lead to cpu_smt_control

Now that we removed ->iterate we don't need to check for either

for ->iterate_shared instead. This will tell us whether we need to
unconditionally take the lock. Not just does it allow us to avoid

locking because of readdir.
Signed-off-by: Christian Brauner <brauner@kernel.org>

All users now just use '->iterate_shared()', which only takes the
directory inode lock for reading.

Filesystems that never got convered to shared mode now instead use a
wrapper that drops the lock, re-takes it in write mode, calls the old
function, and then downgrades the lock back to read mode.

This way the VFS layer and other callers no longer need to care about
filesystems that never got converted to the modern era.

The filesystems that use the new wrapper are ceph, coda, exfat, jfs,
ntfs, ocfs2, overlayfs, and vboxsf.

Honestly, several of them look like they really could just iterate their
directories in shared mode and skip the wrapper entirely, but the point
of this change is to not change semantics or fix filesystems that
haven't been fixed in the last 7+ years, but to finally get rid of the
dual iterators.

I'm looking at the directory handling due to the discussion about f_pos
locking (see commit 79796425: "file: reinstate f_pos locking
optimization for regular files"), and wanting to clean that up.

And one source of ugliness is how we were supposed to move filesystems
over to the '->iterate_shared()' function that only takes the inode lock
for reading many many years ago, but several filesystems still use the
bad old '->iterate()' that takes the inode lock for exclusive access.

See commit 61922694 ("introduce a parallel variant of ->iterate()")
that also added some documentation stating

      Old method is only used if the new one is absent; eventually it will
      be removed.  Switch while you still can; the old one won't stay.

and that was back in April 2016.  Here we are, many years later, and the
old version is still clearly sadly alive and well.

Now, some of those old style iterators are probably just because the
filesystem may end up having per-inode mutable data that it uses for
iterating a directory, but at least one case is just a mistake.

Al switched over most filesystems to use '->iterate_shared()' back when
it was introduced.  In particular, the /proc filesystem was converted as
one of the first ones in commit f50752ea ("switch all procfs
directories ->iterate_shared()").

But then later one new user of '->iterate()' was then re-introduced by
commit 6d9c939d ("procfs: add smack subdir to attrs").

And that's clearly not what we wanted, since that new case just uses the
same 'proc_pident_readdir()' and 'proc_pident_lookup()' helper functions
that other /proc pident directories use, and they are most definitely
safe to use with the inode lock held shared.

So just fix it.

This still leaves a fair number of oddball filesystems using the
old-style directory iterator (ceph, coda, exfat, jfs, ntfs, ocfs2,
overlayfs, and vboxsf), but at least we don't have any remaining in the
core filesystems.

I'm going to add a wrapper function that just drops the read-lock and
takes it as a write lock, so that we can clean up the core vfs layer and
make all the ugly 'this filesystem needs exclusive inode locking' be
just filesystem-internal warts.

I just didn't want to make that conversion when we still had a core user
left.
