From: Christophe JAILLET Date: Thu, 13 Apr 2023 04:06:35 +0000 (+0800) Subject: iommu/vt-d: Do not use GFP_ATOMIC when not needed X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=41d71e09a155a05bd9bec08dd195d8d8e0146ad8;p=linux.git iommu/vt-d: Do not use GFP_ATOMIC when not needed There is no need to use GFP_ATOMIC here. GFP_KERNEL is already used for some other memory allocations just a few lines above. Commit e3a981d61d15 ("iommu/vt-d: Convert allocations to GFP_KERNEL") has changed the other memory allocation flags.
