Subject: [PATCH v4 0/3] mm, netfs,
fscache: Stop read optimisation when folio removed from pagecache
Hi Linus,
How about this then?
I've split the folio_has_private()/filemap_release_folio() call pair
merging into its own patch, separate from the actual bugfix and pulled out
the folio_needs_release() function into mm/internal.h and made
filemap_release_folio() use it. I've also got rid of the bit clearances
from the network filesystem evict_inode functions as they doesn't seem to
be necessary.
I've also added an additional experimental patch to see if the pair in
shrink_folio_list() can be reduced cleanly to just the release call. This
involves making filemap_release_folio() have a three-state return.
David
Changes:
========
ver #4)
- Split has_private/release call pairs into own patch.
- Moved folio_needs_release() to mm/internal.h and removed open-coded
version from filemap_release_folio().
- Don't need to clear AS_RELEASE_ALWAYS in ->evict_inode().
- Added experimental patch to reduce shrink_folio_list().
ver #3)
- Fixed mapping_clear_release_always() to use clear_bit() not set_bit().
- Moved a '&&' to the correct line.
ver #2)
- Rewrote entirely according to Willy's suggestion[1].
