| bufpost | ( | struct _irp * | i | ) |
buffered read completion - see 5.2 21.7.3.1
dirpost may be mixed into this, too? TODO check
| i | irp |
TODO common entrypoint and if bufio bit set only do bufio part?
increment biocnt TODO redo
21.7.3.1 buffered read completion
a little workaround, must be there, but forgot most of it TODO
TODO maybe because some dirio ended up here? TODO check driver configs
invoke movbuf
if mailbox read, call ravail. TODO check read func
dirpost to begin here?
21.7.3.2 common completion
should be either of these iocnt increments
copy eventual diagnostic with movbuf - MISSING
decr ccb_w_ioc - MISSING
if last channel i/o and deaccess pending, call ioc_wakacp - MISSING
set iosb iost etc
do an eventual setting of common event flag - MISSING
deallocate irpes, if any - MISSING?
check for quota bit set, then do ast - MISSING TODO redo
post event flag
queue ast
otherwise free irp
return to sch_astdel

extra global cli TODO check why and still needed?
fetch irp from postprocessing queues

21.7.2 normal i/o completion
checks bufio flag
21.7.2.2 buffered i/o completion
maybe do ioc_mapvblk - MISSING
do mmg_unlock - MISSING

increment diocnt - MISSING?
store bufpost ast in irp and use kast
