[PATCH v13 00/59] ceph+fscrypt: full support

Yet another ceph+fscrypt posting! This time, I've included the revised
sparse read support patches as they have gotten some small revisions and
the main impetus for them is fscrypt anyway.

The main changes since v12:

- rebased onto v5.18-rc1 and fixed up minor merge conflicts
:w

- some minor cleanups and simplifications to the sparse_read
infrastructure

- dropped a patch from Luis that added a legacy v1 key prefix. He's
pursuing a more appropriate userland fix for xfstests instead

- the patch to add has_stable_inodes operation to ceph has been dropped.
That operation is only applicable for special storage hardware, so it
has no purpose on ceph.

- the patch to export new_inode_pseudo has been replaced with one that
changes the I_CREATING test in inode_insert5. This allows us to use
new_inode instead.

For now, I've dropped these from the ceph-client/testing branch, but
I'll plan to merge them again in a couple of weeks once we rebase
ceph-client/master onto a v5.18-rc release (usually around -rc2 or
-rc3).
