crash on big partitions (> 900GB) when sizeof(int) <8 #7

Closed divinity76 closed 5 years ago

divinity76 commented 5 years ago

here is a crash observed by @Ammar7347 , probably caused by the fact that sizeof(int) is 4 and the partition is > 900GB:

starting 3 worker thread(s)... done.
pausing mainthread..
nbdthread waiting for all workers (0/3) to be become ready. (this usually takes a long time - some problem @CAC login system)
upload queue emptied.
worker #2 ready.
worker #3 ready.
worker #1 ready.
all workers (3/3) ready, nbdthread starting NBD_DO_IT.
upload queue no longer empty! (167264)

should probably convert int to int_fast64_t all over the place
