  ceph: fix uninitialized err in ceph_netfs_issue_read() (2026-10-26 14:15:48 +0100)

There is a trivial conflict with "ceph: replace PagePrivate() with
page_private()" patch that went through the akpm tree.  Tal's change
switches that code to folios, so the resolution is to take this side.
I pushed it to for-linus-merged just in case.

----------------------------------------------------------------
The two things of note here are the disablement of inline data support
and a new lazyio mount option to enable LAZYIO behavior globally
(instead of via an ioctl on a per-file basis), both from Xiubo.
Despite being over a decade old, the inline data feature never lost its
experimental status -- it has always been off by default and required
passing --yes-i-really-mean-it flag to be turned on.  It was officially
deprecated in 2020 and is now in the process of being removed on the
MDS side.  For now it's still possible to re-enable it in Kconfig, but
the code will eventually be dropped from the kernel client entirely.

Outside of that we have a number of bug fixes, a series from Tal to
help phase out older page APIs, some cleanups from Max and a large pile
of LLM-based hardening patches.

Xiubo is also back in a maintainer role, replacing Slava.
