Subject: [PATCH] Remove the cap on epoll events |
|
|
|
Currently the code will silently blank out events if there are more |
|
then 512 epoll events, causing them never to be handled at all. This |
|
patch removes the cap on the number of events for epoll_wait, thereby |
|
avoiding this issue. |
|
|
|
(cherry picked from commit 1c724e9e0ec5bc4bf791a3d7b1cf5b955cdb98b2) |
