Still needed in my case on lmi (4.19) and cepheus (4.14) (alioth fine though even 4.19) |
The epoll_pwait2 syscall was introduced in Linux 5.11. Older kernels return ENOSYS when attempting to use this syscall, causing buffer release operations to fail. 12-07 18:05:15.668 2095 2226 E BLASTBufferQueue: epoll_wait error while waiting for buffer release. errno=38 message='Function not implemented' 12-07 18:05:15.668 2095 2226 E BLASTBufferQueue: epoll_wait error while waiting for buffer release. errno=38 message='Function not implemented' Test: Boot device with kernel < 5.11, verify no epoll errors Signed-off-by: Dmitrii <bankersenator@gmail.com>
