[PATCH 00/16] Prepare to remove PG_error

["Matthew Wilcox (Oracle)" <willy@infradead.org>]

These patches remove almost all remaining uses of PG_error from
filesystems and filesystem helper libraries.  In Linus' tree right now,
there is one place which tests the PG_error bit, and that is removed in
the jfs-next tree.  Thus, it is safe to remove all places which set or
clear the PG_error bit since it is not tested.

The ntfs3 patches are allegedly in progress:
https://lore.kernel.org/linux-fsdevel/85317479-4f03-4896-a2e1-d16b912e8b91@paragon-software.com/
so I haven't included a patch here for them.  We also need to remove one
spot in memory-failure that still sets it, so I haven't gone as far as
deleting PG_error yet.  I guess that's for next merge window.
