mainlining shenanigans
036330c914
Before this patch, gfs2 kept track of journal io errors in two places sd_log_error and the SDF_AIL1_IO_ERROR flag in sd_flags. This patch consolidates the two into sd_log_error so that it reflects the first error encountered writing to the journal. In future patches, we will take advantage of this by checking this value rather than having to check both when reacting to io errors. In addition, this fixes a tight loop in unmount: If buffers get on the ail1 list and an io error occurs elsewhere, the ail1 list would never be cleared because they were always busy. So unmount would hang, waiting for the ail1 list to empty. Signed-off-by: Bob Peterson <rpeterso@redhat.com> Reviewed-by: Andreas Gruenbacher <agruenba@redhat.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.
