------------------------------------------------------ From: Anshuman Khandual anshuman.khandual@arm.com Subject: fs/proc/task_mmu: add display flag for VM_MAYOVERLAY Date: Thu, 8 Feb 2024 14:18:05 +0530
VM_UFFD_MISSING flag is mutually exclussive with VM_MAYOVERLAY flag as they both use the same bit position i.e 0x00000200 in the vm_flags. Let's update show_smap_vma_flags() to display the correct flags depending on CONFIG_MMU.
