The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will also be merged in the next major kernel release during the merge window.

The buffer is expressed as a u32 array, yet the extra space for the s64 timestamp was expressed as sizeof(s64)/sizeof(u16). This will result in 2 extra u32 elements. Fix by dividing by sizeof(u32).
