OSD client should ignore cache/overlay flag if got redirect reply. Otherwise, the client hangs when the cache tier is in forward mode. [ idryomov: Redirects are effectively deprecated and no longer used or tested. The original tiering modes based on redirects are inherently flawed because redirects can race and reorder, potentially resulting in data corruption. The new proxy and readproxy tiering modes should be used instead of forward and readforward. Still marking for stable as obviously correct, though. ] Cc: stable@vger.kernel.org URL: https://tracker.ceph.com/issues/23296 URL: https://tracker.ceph.com/issues/36406 Signed-off-by: Jerry Lee <leisurelysw24@gmail.com> Reviewed-by: Ilya Dryomov <idryomov@gmail.com> Signed-off-by: Ilya Dryomov <idryomov@gmail.com>
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.
