 5+Subject: [PATCH] implement posix_getdents adopted for next issue of POSIX
 6+
 7+this interface was added as the outcome of Austin Group tracker issue
 8+697. no error is specified for unsupported flags, which is probably an
 9+oversight. for now, EOPNOTSUPP is used so as not to overload EINVAL.

 5+Subject: [PATCH] fix mismatched type in posix_getdents definition
 6+
 7+commit 1b0d48517f816e98f19111df82f32bfc1608ecec wrongly copied the
 8+getdents return type of int rather than matching the ssize_t used by
 9+posix_getdents. this was overlooked in testing on 32-bit archs but
10+obviously broke 64-bit archs.
