[PATCH] libbpf: Fix map creation flags sanitization

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



As BPF_F_MMAPABLE flag is now conditionnaly set (by map_is_mmapable),
it should not be toggled but disabled if not supported by kernel.

Fixes: 4fcac46c7e10 ("libbpf: only add BPF_F_MMAPABLE flag for data maps with global vars")
