Subject: mm: allow __GFP_RETRY_MAYFAIL in vmalloc
Date: Thu, 12 Feb 2026 17:33:30 +0100 (CET)

The commit 07003531e03c8 ("mm/vmalloc: warn on invalid vmalloc gfp flags")
breaks the device mapper VDO target.  The VDO target calls vmalloc with
__GFP_RETRY_MAYFAIL and this flag is not in the mask of allowed flags.

There is no reason why vmalloc couldn't support __GFP_RETRY_MAYFAIL, so
let's add this flag to GFP_VMALLOC_SUPPORTED.
