I suspect that that's artefact of the initial code submission where the
mostly spaces used for tabs were converted to tabs in some automated manner,
which combined with typedefs removals (also done in automated manner)
like cfs_spinlock_t to spinlock_t and the like produced the result we can see.

Personally I don't care all that much about local variables alignments in the
functions, but alignment of struct members does help, I feel like, so I have been
trying to fix the alignment there whenever I was touching nearby code.
