M0_INTERNAL int m0t1fs_inode_test	(	struct inode *	inode,

In file-systems like m0t1fs or nfs, inode number is not enough to identify a file. For such file-systems structure and semantics of file identifier are file-system specific e.g. fid in case of m0t1fs, file handle for nfs.

m0t1fs_inode_test() and m0t1fs_inode_set() are the implementation of interfaces that are used by generic vfs code, to compare identities of inodes, in a generic manner.
