From: Andrii Nakryiko <andriin@xxxxxx> This patchset fixes a bunch of issues with pahole --reorganize. It should be applied on top of previous patchset with various bitfield fixes. Patch #1 reverts the meaning of member->bit_hole and member->hole to mean "hole after member", which allows for easier adaptation of --reorganize. Patch #2 fixes small bug in class__find_holes() mis-categorizing byte hole as bit hole in certain circumstances. Patch #3 eliminates a lot of ad-hoc adjustments of holes in reorganize code and instead relies on re-calculation of them using class__find_holes(). Patch #4 fixes bug in class__reorganize() causing invalid adjustments of field offsets when moving bitfields around. It could cause BRAIN FART ALERTS during reorganization.
