See http://www.infradead.org/rpr.html __xfs_bunmapi is a bit of an odd place to lock the rtbitmap and rtsummary inodes given that it is very high level code. While this only looks ugly right now, it will become a problem when supporting delayed allocations for RT inodes as __xfs_bunmapi might end up deleting only delalloc extents and thus never unlock the rt inodes. Move the locking into xfs_rtfree_blocks instead (where it will also be helpful once we support extfree items for RT allocations), and use a new flag in the transaction to ensure they aren't locked twice.

See http://www.infradead.org/rpr.html The code to account fdblocks and frextents in xfs_bmap_del_extent_delay is a bit weird in that it accounts frextents before the iext tree manipulations and fdblocks after it. Given that the iext tree manipulations can fail currently that's not really a problem, but still odd. Move the frextent manipulation to the end, and use a fdblocks variable to account of the unconditional indirect blocks and the data blocks only freed for !RT. This prepares for following updates in the area and already makes the code more readable. Also remove the !isrt assert given that this code clearly handles rt extents correctly, and we'll soon reinstate delalloc support for RT inodes.

See http://www.infradead.org/rpr.html When xfs_bmap_del_extent_delay has to split an indirect block it tries to steal blocks from the the part that gets unmapped to increase the indirect block reservation that now needs to cover for two extents instead of one. This works perfectly fine on the data device, where the data and indirect blocks come from the same pool. It has no chance of working when the inode sits on the RT device. To support re-enabling delalloc for inodes on the RT device, make this behavior conditional on not beeing for rt extents. For an RT extent try allocate new blocks or otherwise just give up. Note that split of delalloc extents should only happen on writeback failure, as for other kinds of hole punching we first write back all data and thus convert the delalloc reservations covering the hole to a real allocation. Note that restoring a quota reservation is always a bit problematic, but the force flag should take care of it. That is, if we actually supported quota with the RT volume, which seems to not be the case at the moment.

See http://www.infradead.org/rpr.html Commit aff3a9edb708 ("xfs: Use preallocation for inodes with extsz hints") disabled delayed allocation for all inodes with extent size hints due a data exposure problem. It turns out we fixed this data exposure problem since by always creating unwritten extents for delalloc conversions due to more data exposure problems, but the writeback path doesn't actually support extent size hints when converting delalloc these days, which probably isn't a problem given that people using the hints know what they get. However due to the way how xfs_get_extsz_hint is implemented, it always claims an extent size hint for RT inodes even if the RT extent size is a single FSB. Due to that the above commit effectively disabled delalloc support for RT inodes. Switch xfs_get_extsz_hint to return 0 for this case and work around that in a few places to reinstate delalloc support for RT inodes on file systems with an sb_rextsize of 1.
