Linux 3.1 compat, vfs_fsync()
Preferentially use the vfs_fsync() function. This function was initially introduced in 2.6.29 and took three arguments. As of 2.6.35 the dentry argument was dropped from the function. For older kernels fall back to using file_fsync() which also took three arguments including the dentry. Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov> Issue #52
