Add a comment into fscache_note_page_release() to explain how the
page-release optimisation logic works[1].  It's not entirely obvious as it
has nothing to do with whether or not the netfs file contains data.

FSCACHE_COOKIE_NO_DATA_TO_READ is set if we have no data in the cache yet
(ie. the backing file lookup was negative, the file is 0 length or the
cookie got invalidated).  It means that we have no data in the cache, not
that the file is necessarily empty on the server.

FSCACHE_COOKIE_HAVE_DATA is set once we've stored data in the backing file.
From that point on, we have data we *could* read - however, it's covered by
pages in the netfs pagecache until at such time one of those covering pages
is released.

So if we've written data to the cache (HAVE_DATA) and there wasn't any data
in the cache when we started (NO_DATA_TO_READ), it may no longer be true
that we can skip reading from the cache.

Read skipping is done by cachefiles_prepare_read().

Note that tracking is not done on a per-page basis, but only on a per-file
basis.

Cachefiles keeps track of how much space is available on the backing
filesystem and refuses new writes permission to start if there isn't enough
(we especially don't want ENOSPC happening).  It also tracks the amount of
data pending in DIO writes (cache->b_writing) and reduces the amount of
free space available by this amount before deciding if it can set up a new
write.

However, the old fscache I/O API was very much page-granularity dependent
and, as such, cachefiles's cache->bshift was meant to be a multiplier to
get from PAGE_SIZE to block size (ie. a blocksize of 512 would give a shift
of 3 for a 4KiB page) - and this was incorrectly being used to turn the
number of bytes in a DIO write into a number of blocks, leading to a
massive over estimation of the amount of data in flight.

Fix this by changing cache->bshift to be a multiplier from bytes to
blocksize and deal with quantities of blocks, not quantities of pages.

Fix also the rounding in the calculation in cachefiles_write() which needs
a "- 1" inserting.

If we ever see a touch report with contact count data we initialize
several variables used to read the contact count in the pre-report
phase. These variables are never reset if we process a report which
doesn't contain a contact count, however. This can cause the pre-
report function to trigger a read of arbitrary memory (e.g. NULL
if we're lucky) and potentially crash the driver.

This commit restores resetting of the variables back to default
"none" values that were used prior to the commit mentioned
below.

AES hardware may internally re-classify a contact that it thought was
intentional as a palm. Intentional contacts are reported as "down" with
the confidence bit set. When this re-classification occurs, however, the
state transitions to "up" with the confidence bit cleared. This kind of
transition appears to be legal according to Microsoft docs, but we do
not handle it correctly. Because the confidence bit is clear, we don't
call `wacom_wac_finger_slot` and update userspace. This causes hung
touches that confuse userspace and interfere with pen arbitration.

This commit adds a special case to ignore the confidence flag if a contact
is reported as removed. This ensures we do not leave a hung touch if one
of these re-classification events occured. Ideally we'd have some way to
also let userspace know that the touch has been re-classified as a palm
and needs to be canceled, but that's not possible right now :)

These two values go hand-in-hand and must be valid for the driver to
behave correctly. We are currently lazy about updating the values and
rely on the "expected" code flow to take care of making sure they're
valid at the point they're needed. The "expected" flow changed somewhat
with commit f8b6a747 ("HID: wacom: generic: Support multiple tools
per report"), however. This led to problems with the DTH-2452 due (in
part) to *all* contacts being fully processed -- even those past the
expected contact count. Specifically, the received count gets reset to
0 once all expected fingers are processed, but not the expected count.
The rest of the contacts in the report are then *also* processed since
now the driver thinks we've only processed 0 of N expected contacts.

Later commits such as 7fb0413b (HID: wacom: Use "Confidence" flag to
prevent reporting invalid contacts) worked around the DTH-2452 issue by
skipping the invalid contacts at the end of the report, but this is not
a complete fix. The confidence flag cannot be relied on when a contact
is removed (see the following patch), and dealing with that condition
re-introduces the DTH-2452 issue unless we also address this contact
count laziness. By resetting expected and received counts at the same
time we ensure the driver understands that there are 0 more contacts
expected in the report. Similarly, we also make sure to reset the
received count if for some reason we're out of sync in the pre-report
phase.

Pull more xfs irix ioctl housecleaning from Darrick Wong:
 "Withdraw the XFS_IOC_ALLOCSP* and XFS_IOC_FREESP* ioctl definitions.

  This is the third and final of a series of small pull requests that
  perform some long overdue housecleaning of XFS ioctls. This time,
  we're withdrawing all variants of the ALLOCSP and FREESP ioctls from
  XFS' userspace API. This might be a little premature since we've only
  just removed the functionality, but as I pointed out in the last pull
  request, nobody (including fstests) noticed that it was broken for 20
  years.

  In response to the patch, we received a single comment from someone
  who stated that they 'augment' the ioctl for their own purposes, but
  otherwise acquiesced to the withdrawal. I still want to try to clobber
  these old ioctl definitions in 5.17.

  So remove the header definitions for these ioctls. The just-removed
  implementation has allowed callers to read stale disk contents for
  more than **21 years** and nobody noticed or complained, which implies
  a lack of users aside from exploit programs"

Pull xfs irix ioctl housecleaning from Darrick Wong:
 "Remove the XFS_IOC_ALLOCSP* and XFS_IOC_FREESP* ioctl families.

  This is the second of a series of small pull requests that perform
  some long overdue housecleaning of XFS ioctls. This time, we're
  vacating the implementation of all variants of the ALLOCSP and FREESP
  ioctls, which are holdovers from EFS in Irix, circa 1993. Roughly
  equivalent functionality have been available for both ioctls since
  2.6.25 (April 2008):

   - XFS_IOC_FREESP ftruncates a file.

   - XFS_IOC_ALLOCSP is the equivalent of fallocate.

  As noted in the fix patch for CVE 2021-4155, the ALLOCSP ioctl has
  been serving up stale disk blocks since 2000, and in 21 years
  **nobody** noticed. On those grounds I think it's safe to vacate the
  implementation.

  Note that we lose the ability to preallocate and truncate relative to
  the current file position, but as nobody's ever implemented that for
  the VFS, I conclude that it's not in high demand.

  Linux has always used fallocate as the space management system call,
  whereas these Irix legacy ioctls only ever worked on XFS, and have
  been the cause of recent stale data disclosure vulnerabilities. As
  equivalent functionality is available elsewhere, remove the code"

  attributes on XFS files. The DMAPI support has never been merged
  upstream and the implementation of FSSETDM itself was removed two
  years ago, so let's withdraw it completely.

   - Withdraw the ioctl definition for the FSSETDM ioctl"
