Hi Linus,
In the course of preparing the folio changes for iomap for next merge
window, we discovered some problems that would be nice to address now:
- Renaming multi-page folios to large folios.
mapping_multi_page_folio_support() is just a little too long, so
we settled on mapping_large_folio_support(). That meant renaming,
eg folio_test_multi() to folio_test_large().
- I hadn't included folio wrappers for zero_user_segments(), etc.
Also, multi-page^W^W large folio support is now independent of
CONFIG_TRANSPARENT_HUGEPAGE, so machines with HIGHMEM always need to
fall back to the out-of-line zero_user_segments().
- The build bots finally got round to telling me that I missed a
couple of architectures when adding flush_dcache_folio(). Christoph
suggested that we just add linux/cacheflush.h and not rely on
asm-generic/cacheflush.h.
These changes have been in linux-next for the last week with no new
squawks.
The following changes since commit 8ab774587903771821b59471cc723bba6d893942:
