From: "Pratyush Yadav (Google)" <[email protected]> Hi,
This series adds some tests for memfd preservation across a live update. Currently memfd is only tested indirectly via luo_kexec_simple or luo_multi_session. Add a dedicated test suite for it. Patches 1 and 2 are preparatory, adding base framework and helpers, and the other patches each add a test. Some of the code is taken from the libluo patches [0] I sent a while ago.
