I /am/ beginning to wonder, though -- seeing as Christoph and Matthew both have very large patchsets changing things in fs/iomap/, how would you like those landed? Christoph's iterator refactoring looks like it could be ready to go for 5.15. Matthew's folio series looks like a mostly straightforward conversion for iomap, except that it has 91 patches as a hard dependency. Since most of the iomap changes for 5.15 aren't directly related to folios, I think I prefer iomap-for-next to be based directly off -rcX like usual, though I don't know where that leaves the iomap folio conversion. I suppose one could add them to a branch that itself is a result of the folio and iomap branches, or leave them off for 5.16? Other ideas? --D
