db80696d21 vfs/poll: fix timeout calculation 2017-06-09 11:37:30 -06:00

e3d865f6c2 In last changed to poll(),cConverted timeout to unsigned to eliminate the possibility of overflow of signed overflow. 2017-04-28 11:02:54 -06:00

37ca797d1c vfs/poll: round timeout up to next full tick. Calling poll() with timeout less than half tick (thus MSEC2TICK(timeout) => 0) caused returning error with EAGAIN. Instead of rounding timeout down, value should be rounded up. Open Group spec for poll says: "Implementations may place limitations on the granularity of timeout intervals. If the requested timeout interval requires a finer granularity than the implementation supports, the actual timeout interval will be rounded up to the next supported value." 2017-04-28 08:42:37 -06:00

c9ca97b4b5 cancellation points are basically function. More tested is needed and additional cancellation points must be implemented before this can be merged back to master. 2016-12-09 12:01:18 -06:00
