            Bug ID: 29657
           Summary: Incorrect struct stat for 64-bit time on linux/generic
                    platforms
           Product: glibc
           Version: 2.36
            Status: NEW
          Severity: normal
          Priority: P2
         Component: libc
          Assignee: unassigned at sourceware dot org
          Reporter: jsm28 at gcc dot gnu.org
                CC: drepper.fsp at gmail dot com
  Target Milestone: ---
              Host: csky*-linux* nios2*-linux*

sysdeps/unix/sysv/linux/generic/bits/struct_stat.h is missing the condition=
als
to use bits/struct_stat_time64_helper.h in the __USE_TIME_BITS64 case.  This
means that platforms using linux/generic but with __TIMESIZE =3D=3D 32 (i.e=
. csky
and nios2, I think) get the wrong version of struct stat for 64-bit time, s=
ince
the actual function implementations use struct __stat64_t64 which does use
bits/struct_stat_time64_helper.h, so the type declared in the installed hea=
ders
is inconsistent with the implementation.
