11 contains some kernel-specific sparse information.
14 Using sparse for typechecking
27 there because sparse will complain about casting to/from a bitwise type,
48 constant zero as a bitwise integer type without sparse ever complaining.
54 Using sparse for lock checking
57 The following macros are undefined for gcc and defined during a sparse
58 run to use the "context" tracking feature of sparse, applied to
59 locking. These annotations tell sparse when a lock is held, with
71 sparse would otherwise report a context imbalance.
