[GIT PULLBOMB v5.6] xfs: metadata directories and realtime groups

["Darrick J. Wong" <djwong@kernel.org>]

Hi Carlos,

Please pull these fully reviewed patchsets for kernel 6.13.  This
patchbomb corrects numerous paperwork errors in the v5.5 submission so
that we can pass linux-next linter.

I have corrected my stgit wrapper program to invoke git checkpatch
before issuing pull requests.  Despite its name, this means I now have
automated checks for tagging errors in git commits.  Freeform text
fields that require a lot of parsing cleverness to check and that can be
corrupted easily buc*********.

The following excerpted range diff shows the differences between last
week's PRs and this week's:

    @@ Commit message
         this patch, we'd invoke xfs_free_eofblocks on first close if anything
         was in the CoW fork.  Now we don't do that.
     
         Fix the problem by reverting the removal of the i_delayed_blks check.

         fsmap irec structure that contains exactly the data we need, once.
     
         Note that we actually do need rm_startblock for rmap key comparisons
         when we're actually querying an rmap btree, so leave that field but
         document why it's there.

    @@ Commit message
     
         Note that this changes the rmblocks calculation method to be based
         on the passed in rblocks and extsize and not the explicitly passed
         one, but both methods will always lead to the same result.  The new
         version just does a little bit more math while being more general.

110:  b91afef724710e ! 110:  2a81329aa08d66 xfs: don't merge ioends across RTGs
    @@ Commit message
         Unlike AGs, RTGs don't always have metadata in their first blocks, and
         thus we don't get automatic protection from merging I/O completions
         across RTG boundaries.  Add code to set the IOMAP_F_BOUNDARY flag for
         ioends that start at the first block of a RTG so that they never get
         merged into the previous ioend.
