| H A D | bus_dma.9 | diff 4d855643d1c64e7a04ec31e128c7773701610bfa Wed Aug 25 01:09:57 CEST 2004 Warner Losh <imp@FreeBSD.org> Clarify what the lockfunc is used for. When it will be called and
when it won't be called. The old wording was correct, but not
sufficiently specific to understand when and how it would be called.
The new wording describes the current implementation's usage (which
should be updated if other appropriate times are decided upon),
specifically that it is called only when the load operation is
deferred to keep the locking state consistent. When the operation
isn't deferred, the calling routine is assumed to have a coherent
locking world.
