+Subject: [PATCH] Ignore pwritev/pwrite64 tests on musl
+
+musl uses wrappers for pwritev and pwrite64 using
+pwritev2 syscall [1], however the test exepcts that the
+program will call pwritev and pwrite64 ( glibc behavior )
+
+This can be fixed if the function calls are changed to
+use syscall() API directly, but that needs change upstream [2]

+Subject: [PATCH] tests: fix uio.test with musl-libc
+
+musl-libc handles the pwrite calls differently than glibc, making
+the uio test fail.  Using glibc, there are separated pwrite and pwritev
+calls, however musl uses only pwritev2 for both pwrite and pwritev.
+
+To account to this difference, modify the expected matching regexp
+to also match the musl output (append it with an OR).
