Linux 4.16 compat: inode_set_iversion()
A new interface was added to manipulate the version field of an inode. Add a inode_set_iversion() wrapper for older kernels and use the new interface when available. The i_version field was dropped from the trace point due to the switch to an atomic64_t i_version type. Reviewed-by: Olaf Faaland <[email protected]> Reviewed-by: Giuseppe Di Natale <[email protected]> Reviewed-by: Chunwei Chen <[email protected]> Signed-off-by: Brian Behlendorf <[email protected]> Closes #7148
