Subject: mm: shmem: use signed int for version handling in casefold option
Date: Sat, 11 Jan 2025 15:31:30 +0000
Fixes an issue where the use of an unsigned data type in
`shmem_parse_opt_casefold()` caused incorrect evaluation of negative
conditions.

Fixes: 58e55efd6c72 ("tmpfs: Add casefold lookup support")
