WebFor example, a 4-bit bitfield encodes BTF_INT_BITS() equals to 4. The btf_type.size * 8 must be equal to or greater than BTF_INT_BITS() for the type. The maximum value of BTF_INT_BITS() is 128. The BTF_INT_OFFSET() specifies the starting bit offset to calculate values for this int. For example, a bitfield struct member has: WebApr 10, 2024 · The widely used structure is carefully laid out so that it doesn't waste any bits - there are 16 + 8 + 8 bits, then 32-bit union, and then union of something that needs on 64-bit hosts 64-bit alignment. So header nicely 64 bits before the variable sized payloads. The above change grows that to 16 + 16 + 8 bits, the 32-bit union needs 32-bit ...

The bit field allows the packing of data in a structure or union and prevents the wastage of memory.
