Hi all,

Today's linux-next merge of the block tree got a conflict in:

  drivers/block/zram/zram_drv.c

between commit:

  58652f2b6d21 ("zram: permit only one post-processing operation at a time")

from the mm-stable tree and commit:

  5fcfcd51ea1c ("zram: fix NULL pointer in comp_algorithm_show()")

from the block tree.

I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging.  You may also want to consider cooperating
with the maintainer of the conflicting tree to minimise any particularly
complex conflicts.

Cheers,

Hi all,

Today's linux-next merge of the block tree got a conflict in:

  mm/page_io.c

between commit:

  d590df11be0f1 ("mm/page_io: rename swap_iocb fields for clarity")

from the mm-stable tree and commit:

  ca36c1aaee095 ("block: Add bvec_folio()")

from the block tree.

I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging.  You may also want to consider cooperating

Thanks; your resolution is clearly correct.  If it'd be easier, we can
just drop the hunk touching mm/page_io.c from the block tree and I can
submit a separate patch next merge window to the mm tree.  But the
resolution seems straightforward enough that maybe just keep it.
