Linus Torvalds 7c7fdaf6ad fscrypt updates for 5.11
This release there are some fixes for longstanding problems, as well as
 some cleanups:
 
 - Fix a race condition where a duplicate filename could be created in an
   encrypted directory if a syscall that creates a new filename raced
   with the directory's encryption key being added.
 
 - Allow deleting files that use an unsupported encryption policy.
 
 - Simplify the locking for 'struct fscrypt_master_key'.
 
 - Remove kernel-internal constants from the UAPI header.
 
 As usual, all these patches have been in linux-next with no reported
 issues, and I've tested them with xfstests.
