[2.6.18-rc5 PATCH]: aio cleanup

From: Yi Yang
Date: Wed Aug 30 2006 - 10:16:42 EST


As Zach Brown said, a cleanup patch is reasonable. Here it is.

This patch extracts the common part from aio_fsync and aio_fdsync
and define a new inlined function aio_xsync, then aio_fsync and aio_fdsync just call aio_xsunc in the almost same way except second
argument is different, one is 1 and another 0.
