The first patch seems to be where Gao Xiang, Christoph and I have settled for immediate support of EROFS tails. The second is a prequel to the folio work. Because folios are variable size, if we have, eg, an 8.1KiB file, we must support reading the first two pages of the folio from blocks and then the last 100 bytes from the tailpack. That means effectively supporting block size < page size. I thought it cleaner to separate it out, and maybe that can go in this round. The folio patches are rebased on top of all this; if you're hungry to see them, they can be found at https://git.infradead.org/users/willy/pagecache.git/shortlog/refs/heads/folio as usual. I haven't applied all the R-b yet (and I should probably figure out which ones still apply since I did some substantial changes to a couple of the patches).
