Before this patch, the error path of function gfs2_create_inode would always calls gfs2_glock_put for the inode glock. That's good for inodes that are free. But after they've been added to the vfs inodes, errors will cause the inode to be evicted, and the evict will do the glock put for us. If we do a glock put again, we can try to free the glock while there are still references to it, e.g. revokes pending for the transaction that created it. This patch adds a check: if (free_vfs_inode) before the put, thus solving the problem. Signed-off-by: Bob Peterson <rpeterso@redhat.com> 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 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.
