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));
> + /* fall through */

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:
