+CentOS 5.8 kernels and headers support the sync_file_range() system call,
+but glibc 2.5 doesn't provide the syscall stub.  It appears that this
+problem is known but will never be fixed:

+  Bug 518581 - [RHEL5] glibc misses sync_file_range syscall interface 
+
+  Status:       CLOSED CANTFIX

+
+  Description of problem:
+
+  glibc misses sync_file_range syscall interface.  The header file and
+  man page both say 'sync_file_range' should exist.  From man page,
+  sync_file_range should exist sinc kernel-2.6.17
+
+  Andreas Schwab 2009-08-21 03:24:24 EDT
+
+  It has only been added to glibc 2.6, and cannot be backported due to
+  ABI breakage.  You can always fall back to syscall(3).
+
+  Ulrich Drepper 2009-11-22 22:19:55 EST
+
+  As comment #1 says, no chance to backport this.
+
+  See the syscall man page for instructions.

+
+  then why document it if it's broken and you're not going to fix it?
+  .. might want to FTFM over at sync_file_range(2) - in the meantime -
+  borrowing from glibc 2.6 .. any thoughts on this implementation for a
+  hacky workaround for those still on your "ancient releases" .. (eg:
+  RHEL5.3)?:
+
+  #ifdef ULI_WONT_FIX_THIS_IN_GLIBC2.5
+  #define NR_sync_file_range 277
+  int sync_file_range (int fd, __off64_t from, __off64_t to, unsigned int flags)
+  {
+    return syscall (NR_sync_file_range, fd,
+                           __LONG_LONG_PAIR ((long) (from >> 32), (long) from),
+                           __LONG_LONG_PAIR ((long) (to >> 32), (long) to),
+                           flags);
+  }
+  #endif
+
+  assuming of course that you're on an x86_64 and include/asm-
+  x86_64/unistd.h has the correct entry
+
+  (fwiw - fio is starting to use this now)
+
+Rather than attempting to provide an implementation using syscall(),
+we take the more conservative route and ignore header support for
+sync_file_range() flags when the glibc version is <= 2.5.
