-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
- Last Closed: 2009-11-22 22:19:55

- 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.
