[LTP] [PATCH 0/2] Coverage for MADV_GUARD_* features

[Andrea Cervesato]

Kernel 6.13 has introduced a new feature for madvise() which causes
SIGSEGV when a memory advised with MADV_GUARD_INSTALL has been used.
To release memory, MADV_GUARD_REMOVE must be used.

This patch series adds coverage for both MADV_GUARD_INSTALL and
MADV_GUARD_REMOVE in madvise12.
