Hi, the attached patch makes use of the ST_NOATIME flag I just added in glibc for statvfs/fstatvfs, by making libdiskfs expose it if needed in its file_statfs implementation. (This will automatically cover ext2fs and tmpfs, for example).
OK to push? -- Pino Toscano

Subject: [PATCH] libdiskfs: expose the ST_NOATIME flag
Expose ST_NOATIME as flag (if available in glibc) if diskfs is set in noatime
mode.
* libdiskfs/file-statfs.c (diskfs_S_file_statfs): Set ST_NOATIME if
_DISKFS_NOATIME is set.
