Hi!
I'm sending another iteration of the encrypted snapshot names patch. This patch assumes PR#45224 [1] to be merged as it adds support for the alternate names.
Two notes:
1. Patch 0001 is just a small fix from another fscrypt patch. It's probably better to simply squash it.
2. I'm not sure how easy it is to hit the UAF fixed by patch 0002. I can reproduce it easily by commenting the code that adds the DCACHE_NOKEY_NAME flag in patch 0003.
Any comments are welcome (including for the PR mentioned above, of course).
