Subject: [PATCH 0/2] iomap: make inline data support more flexible
Date: Sat, 24 Jul 2021 04:44:33 +0100	[thread overview]
Message-ID: <20210724034435.2854295-1-willy@infradead.org> (raw)

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).

Gao Xiang (1):
  iomap: Support file tail packing

Matthew Wilcox (Oracle) (1):
  iomap: Support inline data with block size < page size
