This patch is an attempt to force some consistency in quota sync processing. Two functions (qd_fish and gfs2_quota_unlock) called qd_check_sync, after which they both called bh_get, and if that failed, they took the same steps to undo the actions of qd_check_sync. This patch introduces a new function, qd_bh_get_or_undo, which performs the same steps, reducing code redundancy.

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.
