Fork of alistair23 Linux kernel for reMarkable from https://github.com/alistair23/linux

afs_check/update_server_record() should be setting fc->error rather than
fc->ac.error as they're called from within the cursor iteration function.
afs_fs_cursor::error is where the error code of the attempt to call the
operation on multiple servers is integrated and is the final result,
whereas afs_addr_cursor::error is used to hold the error from individual
iterations of the call loop. (Note there's also an afs_vl_cursor which
also wraps afs_addr_cursor for accessing VL servers rather than file
servers).
Fix this by setting fc->error in the afs_check/update_server_record() so
that any error incurred whilst talking to the VL server correctly
propagates to the final result.
This results in:
kAFS: Unexpected error from FS.StoreData -512
being seen, even though the store-data op is non-interruptible. The error
is actually coming from the server record update getting interrupted.

README
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
