Hi,

I notice a regression report on Bugzilla [1]. Quoting from it:

> after updating from 6.2.x to 6.3.x, vmalloc error messages started to appear in the dmesg
>
>
>
> # free
> total used free shared buff/cache available
> Mem: 16183724 1473068 205664 33472 14504992 14335700
> Swap: 16777212 703596 16073616
>
>
> (zswap enabled)

See bugzilla for the full thread and attached dmesg.

On the report, the reporter can't perform the required bisection,
unfortunately.

Anyway, I'm adding it to regzbot:

#regzbot introduced: v6.2..v6.3 https://bugzilla.kernel.org/show_bug.cgi?id=217466
#regzbot title: btrfs_work_helper dealloc error in v6.3.x

Thanks.
