Subject: [PATCH] xen/grant-table: Fix incorrect gnttab_dma_free_pages() pr_debug message
Date: Fri, 2 Nov 2018 14:04:23 +0000 [thread overview]
Message-ID: <1541167463-32024-1-git-send-email-Liam.Merwick@oracle.com> (raw)
If a call to xenmem_reservation_increase() in gnttab_dma_free_pages()
fails it triggers a message "Failed to decrease reservation..." which
should be "Failed to increase reservation..."
Fixes: 9bdc7304f536 ('xen/grant-table: Allow allocating buffers suitable for DMA')
