[LTP] [PATCH v2 0/3] LTP reproducer on broken IMA on overlayfs

[Petr Vorel]

Hi,

this is a second version of patch demonstrating a bug on overlayfs when
combining IMA with EVM. There is ongoing work made by Ignaz Forster and
Fabian Vogt [1] [2], IMA only behavior was already fixed [3].

Main patch is the last one (previous are just a cleanup and not changed).

Kind regards,
Petr
