# commit 87066fdd2e30fe9dd531125d95257c118a74617e
# Author: Linus Torvalds <torvalds@linux-foundation.org>
# Date:   Sun Oct 24 09:48:33 2021 -1000
# 
#     Revert "mm/secretmem: use refcount_t instead of atomic_t"
#     
#     This reverts commit 110860541f443f950c1274f217a1a3e298670a33.
#     
#     Converting the "secretmem_users" counter to a refcount is incorrect,
#     because a refcount is special in zero and can't just be incremented (but
#     a count of users is not, and "no users" is actually perfectly valid and
#     not a sign of a free'd resource).
