Because the second and third patches have conflicting dependencies, these patches are put together. --- v3 changes: * split free_cnt count and spin lock optimization into two patches v2 changes: * review suggested changes Tianjia Zhang (5): selftests/x86: Simplify the code to get vdso base address in sgx x86/sgx: Optimize the locking range in sgx_sanitize_section() x86/sgx: Optimize the free_cnt count in sgx_epc_section x86/sgx: Allows ioctl PROVISION to execute before CREATE x86/sgx: Remove redundant if conditions in sgx_encl_create arch/x86/kernel/cpu/sgx/driver.c | 1 + arch/x86/kernel/cpu/sgx/ioctl.c | 9 +++++---- arch/x86/kernel/cpu/sgx/main.c | 13 +++++-------- tools/testing/selftests/sgx/main.c | 24 ++++-------------------- 4 files changed, 15 insertions(+), 32 deletions(-)
