We can't hold mark_lock while calling fsck_err() - that's a deadlock, mark_lock is meant to be a leaf node lock. It's also unnecessary for gc_bucket() and bucket_gen(); rcu suffices since the bucket_gens array describes its size, and we can't race with device removal or resize during gc/fsck since that takes state lock.

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 reStructuredText 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.
