[Ocfs2-devel] [PATCH 12/30] ocfs2: Define FS_RENAME_DOES_D_MOVE

[Sunil Mushran]

Commit 349457ccf2592c14bdf13b6706170ae2e94931b1 in mainline defines macro
FS_RENAME_DOES_D_MOVE to allow fs to call d_move() during rename().
This patch allows one to build ocfs2 with kernels having/not having
this change.
