Hello Andrew,

It seems like the changes in mm/dmapool.c somehow got omitted in this PR.

$ git log --oneline 4d4b6d66db63ceed399f1fb1a4b24081d2590eb1 --not v6.3 mm/dmapool.c
2d55c16c0c54 dmapool: create/destroy cleanup
a4de12a032fa dmapool: link blocks across pages
9d062a8a4c6d dmapool: don't memset on free twice
887aef615818 dmapool: simplify freeing
2591b516533b dmapool: consolidate page initialization
36d1a28921a4 dmapool: rearrange page alloc failure handling
52e7d5653979 dmapool: move debug code to own functions
19f504584038 dmapool: speedup DMAPOOL_DEBUG with init_on_alloc
347e4e44c0a9 dmapool: cleanup integer types
65216545436b dmapool: use sysfs_emit() instead of scnprintf()
7f796d141c07 dmapool: remove checks for dev == NULL

$ git diff 4d4b6d66db63ceed399f1fb1a4b24081d2590eb1 v6.3 mm/dmapool.c
<empty>

It seems like the final commit, 2d55c16c0c54 ("dmapool: create/destroy
cleanup") somehow reverted all the previous changes to this file.


Looking at how that patch looked like on the list:
https://patchwork.kernel.org/project/linux-mm/patch/20230126215125.4069751-13-kbusch@meta.com/
the diff is way smaller than what can be seen in 2d55c16c0c54.

Additionally, you might want to pick up:
https://patchwork.kernel.org/project/linux-mm/patch/20230221165400.1595247-1-kbusch@meta.com/
as it has a Fixes tag that references one of the commits above.


Kind regards,
Niklas
