Currently at mount time, the recovery code looks up the current log head and, if necessary, replays the log and writes a recovery header to indicate that the log is clean. It does that for each log that may need recovery. We also know that our own log will always be checked as part of that process. Then, the mount code looks up the log head of our own log again. The double log head lookup can be costly, but more importantly, it is unnecessary because we can trivially compute the position of the log head after recovery; all we need to do for that is bump the position and lh_sequence by one when writing a recovery header. With that in mind, move the call to gfs2_log_pointers_init() into gfs2_recover_func() and get rid of the double lookup in gfs2_make_fs_rw(). Signed-off-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 reStructuredText 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.
