Subject: [PATCH 09/12] sysdeps: tst-bz21269: handle ENOSYS & skip
|
|
appropriately
|
|
|
|
SYS_modify_ldt requires CONFIG_MODIFY_LDT_SYSCALL to be set in the kernel, which
|
|
some distributions may disable for hardening. Check if that's the case (unset)
|
|
and mark the test as UNSUPPORTED if so.
|
