Disentangle the dqrele_all inode grab code from the "generic" inode walk grabbing code, and and use the opportunity to document why the dqrele grab function does what it does. Since xfs_inode_walk_ag_grab is now only used for blockgc, rename it to reflect that. Ultimately, there will be four reasons to perform a walk of incore inodes: quotaoff dquote releasing (dqrele), garbage collection of speculative preallocations (blockgc), reclamation of incore inodes (reclaim), and deferred inactivation (inodegc). Each of these four have their own slightly different criteria for deciding if they want to handle an inode, so it makes more sense to have four cohesive igrab functions than one confusing parameteric grab function like we do now.

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.
