please split the assert, e.g.:

	ASSERT(xfs_isilocked(ip, XFS_IOLOCK_SHARED | XFS_IOLOCK_EXCL));

	switch (reason) {
+	case BREAK_UNMAPI:
		ASSERT(xfs_isilocked(ip, XFS_MMAPLOCK_EXCL));

I have to say I'd prefer BREAK_UNMAP over BREAK_UNMAPI given that weird
I suffix doesn't buy us anything, but that's just a minor issue.

Otherwise looks good:
