mainline inclusion from mainline-v5.14-rc1 commit 040efd1c35f93787cbd26be6fc6493592571f424 category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I4SIGI CVE: NA
Often, it's useful to check whether /proc/self/maps looks sane when dealing with memory mapped objects, especially when they are JIT'ish dynamically constructed objects. Therefore, dump "/dev/sgx_enclave" matching lines from the memory map in FIXTURE_SETUP().
