+Subject: [PATCH] tests: fix `S_IFMT` undeclared at `statx.c`
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+`S_IFMT` is declared in `sys/stat.h`, but we cannot include this header
+because it redeclares the `statx` function with different argument
+types. Therefore, we define `S_IFMT` ourselves, in the same way as the
+other definitions.
+
+Closes: #17293
+
+Upstream: https://github.com/openzfs/zfs/commit/634c172ee89f5303493a75dc7ff55e0a355b503a
