If processing recovered log intent items fails, we need to cancel all the unprocessed recovered items immediately so that a subsequent AIL push in the bail out path won't get wedged on the pinned intent items that didn't get processed. This can happen if the log contains (1) an intent that gets and releases an inode, (2) an intent that cannot be recovered successfully, and (3) some third intent item. When recovery of (2) fails, we leave (3) pinned in memory. Inode reclamation is called in the error-out path of xfs_mountfs before xfs_log_cancel_mount. Reclamation calls xfs_ail_push_all_sync, which gets stuck waiting for (3). Therefore, call xlog_recover_cancel_intents if _process_intents fails. Signed-off-by: Darrick J.

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.
