Subject: Fwd: vmalloc error: btrfs-delalloc btrfs_work_helper [btrfs] in
 kernel 6.3.x

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

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.
