Hello Kernel maintainers,

Due to a bug in tmpfs handling of inodes, it's possible to run into inode
collisions on heavily loaded tmpfs filesystems. This problem is described in
detail in
https://chrisdown.name/2021/07/02/tmpfs-inode-corruption-introducing-inode64.html
and has been applied by default in Arch.

Considering the potential for extremely hard to track failures and the fact that
this has been widely deployed already, I suggest that we enable
CONFIG_TMPFS_INODE64 by default.

I will be making an MR in Gitlab to this effect.

Sincerely,
