Of the patches I sent last week, there are the ones that haven't gotten an RVB tag yet: [PATCH 2/4] xfs: hoist freeing of rt data fork extent mappings [PATCH 1/8] xfs: fix units conversion error in [PATCH 4/7] xfs: create helpers to convert rt block numbers to rt [PATCH 5/7] xfs: convert do_div calls to xfs_rtb_to_rtx helper calls [PATCH 3/8] xfs: convert open-coded xfs_rtword_t pointer accesses to [PATCH 5/8] xfs: create helpers for rtbitmap block/wordcount [PATCH 6/8] xfs: use accessor functions for bitmap words [PATCH 8/8] xfs: use accessor functions for summary info words Someone else ought to have a look at the m_rsum_cache changes in "xfs: cache last bitmap block in realtime allocator". --D > The new head of the rtalloc-speedups-6.7 branch is commit: > > 8468dc886e05 xfs: don't look for end of extent further than necessary in xfs_rtallocate_extent_near() > > 36 new commits: > > Darrick J.
