Keep glocks in their hash table until they are freed instead of removing them when their last reference is dropped. This allows to wait for any previous instances of a glock to go away in gfs2_glock_get before creating a new glocks. Special thanks to Andy Price for finding and fixing a problem which also required us to delete the rcu_read_unlock from the error case in function gfs2_glock_get.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
