In xfs_qm_dqalloc, we join the locked quota inode to the transaction we use to allocate blocks. If the allocation or mapping fails, we're not allowed to unlock the inode because the transaction code is in charge of unlocking it for us. Therefore, remove the iunlock call to avoid blowing asserts about unbalanced locking + mount hang. Found by corrupting the AGF and allocating space in the filesystem (quotacheck) immediately after mount. The upcoming agfl wrapping fixup test will trigger this scenario. Signed-off-by: Darrick J.

README
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.
