Daniel Verkamp 5656c124af devices: block: fix seccomp failures from free() ... It looks like free() will sometimes try to open /proc/sys/vm/overcommit_memory in order to decide whether to return freed heap memory to the kernel; change the seccomp filter to fail the open syscalls with an error code (ENOENT) rather than killing the process. Also allow madvise to free memory for the same free() codepath.
