Well I don't know how I did this, sorry. The patch "dmapool: create/destroy cleanup" was OK in mm-unstable (and linux-next) from Jan 26 to Feb 26, so the series has had decent linux-next testing. It became messed up on Feb 26. I've reconstituted dmapool: remove checks for dev == NULL dmapool: use sysfs_emit() instead of scnprintf() dmapool: cleanup integer types dmapool: speedup DMAPOOL_DEBUG with init_on_alloc dmapool: move debug code to own functions dmapool: rearrange page alloc failure handling dmapool: consolidate page initialization dmapool: simplify freeing dmapool: don't memset on free twice dmapool: link blocks across pages dmapool: create/destroy cleanup and pushed the result out to the mm-unstable branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm. 3a64f2e22553 dmapool: create/destroy cleanup 1d1e67d45a37 dmapool: link blocks across pages 7e54c3f0e123 dmapool: don't memset on free twice cb569a63de3b dmapool: simplify freeing 874938254ae7 dmapool: consolidate page initialization b97304656ad5 dmapool: rearrange page alloc failure handling c31e8ec45299 dmapool: move debug code to own functions 1e05e5bdce74 dmapool: speedup DMAPOOL_DEBUG with init_on_alloc 7ea3ff961459 dmapool: cleanup integer types adf388b29d25 dmapool: use sysfs_emit() instead of scnprintf() 8491f7f301ad dmapool: remove checks for dev == NULL Please check that all is as expected. > 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. That fix has been folded into "dmapool: link blocks across pages".
