| Subject: xen/grant-table: Fix incorrect gnttab_dma_free_pages() pr_debug |
| message |
| |
| [ Upstream commit d9cccfa7c4d1d9ef967ec9308df7304a18609b30 ] |
| |
| 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') |
