Pull more fscache updates from David Howells:
"A set of fixes and minor updates for the fscache rewrite:

- Fix mishandling of volume collisions (the wait condition is
inverted and so it was only waiting if the volume collision was
already resolved).

- Fix miscalculation of whether there's space available in
cachefiles.

- Make sure a default cache name is set on a cache if the user hasn't
set one by the time they bind the cache.

- Adjust the way the backing inode is presented in tracepoints, add a
tracepoint for mkdir and trace directory lookup.

- Add a tracepoint for failure to set the active file mark.

- Add an explanation of the checks made on the backing filesystem.

- Check that the backing filesystem supports tmpfile.

- Document how the page-release cancellation of the read-skip
optimisation works.

And I've included a change for netfslib:

- Make ops->init_rreq() optional"

mm: remove cleancache

2022-01-22T06:33:38+00:00

Patch series "remove Xen tmem leftovers".

Since the removal of the Xen tmem driver in 2019, the cleancache hooks
are entirely unused, as are large parts of frontswap.  This series
against linux-next (with the folio changes included) removes
cleancaches, and cuts down frontswap to the bits actually used by zswap.

This patch (of 13):

The cleancache subsystem is unused since the removal of Xen tmem driver
in commit 814bbf49dcd0 ("xen: remove tmem driver").

fs: proc: store PDE()->data into inode->i_private

2022-01-22T06:33:37+00:00

PDE_DATA(inode) is introduced to get user private data and hide the
layout of struct proc_dir_entry.  The inode->i_private is used to do the
same thing as well.  Save a copy of user private data to inode->
i_private when proc inode is allocated.  This means the user also can
get their private data by inode->i_private.

Introduce pde_data() to wrap inode->i_private so that we can remove
PDE_DATA() from fs/proc/generic.c and make PTE_DATE() as a wrapper of
pde_data().  It will be easier if we decide to remove PDE_DATE() in the
future.

this is doing.
