Hello, BTW, nohang in pre-release versions tried to clean tmpfs: https://github.com/hakavlad/nohang-extra/blob/master/nohang_old#L49

We can easy detect `tmpfs` overflow by `Shmem` in `/proc/meminfo`: ``` Shmem %lu (since Linux 2.6.32) Amount of memory consumed in tmpfs(5) filesystems. ``` http://man7.org/linux/man-pages/man5/proc.5.html tmpfs can be filled with...
