+ hurd: Fix pwritev*
+
+ This follows c45d78aac ('posix: Fix generic p{read,write}v buffer
allocation
+ (BZ#22457)'), which made pwritev to use __mmap instead of __posix_memalign,
+ but didn't pass PROT_READ to it, while the pwrite() call does need to
+ read the data we have just copied over.
+
+ * sysdeps/posix/pwritev_common.c: Add PROT_READ to __mmap prot.
