Unlinked list recovery requires errors removing the inode the from the unlinked list get fed back to the main recovery loop. Now that we offload the unlinking to the inodegc work, we don't get errors being fed back when we trip over a corruption that prevents the inode from being removed from the unlinked list. This means we never clear the corrupt unlinked list bucket, resulting in runtime operations eventually tripping over it and shutting down. Fix this by collecting inodegc worker errors and feed them back to the flush caller. This is largely best effort - the only context that really cares is log recovery, and it only flushes a single inode at a time so we don't need complex synchronised handling. Essentially the inodegc workers will capture the first error that occurs and the next flush will gather them and clear them. The flush itself will only report the first gathered error. In the cases where callers can return errors, propagate the collected inodegc flush error up the error handling chain. In the case of inode unlinked list recovery, there are several superfluous calls to flush queued unlinked inodes - xlog_recover_iunlink_bucket() guarantees that it has flushed the inodegc and collected errors before it returns. Hence nothing in the calling path needs to run a flush, even when an error is returned. Signed-off-by: Dave Chinner <dchinner@redhat.com> Reviewed-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.
