vhost: support event index

2011-05-30T01:44:15+00:00

vhost: copy_from_user -> __copy_from_user

2011-03-08T16:03:05+00:00

copy_from_user is pretty high on perf top profile, replacing it with __copy_from_user helps. It's also safe because we do access_ok checks during setup. Signed-off-by: Michael S. Tsirkin

vhost: Cleanup vhost.c and net.c

2011-03-08T16:02:47+00:00

Minor cleanup of vhost.c and net.c to match coding style. Signed-off-by: Krishna Kumar Signed-off-by: Michael S. Tsirkin

vhost: fix signed/unsigned comparison

2011-01-10T08:03:39+00:00

To detect that a sequence number is done, we are doing math on unsigned integers so the result is unsigned too. Not what was intended for the <= comparison. The result is user stuck forever in flush call. Convert to int to fix this. Further, get rid of ({}) to make code clearer. Signed-off-by: Michael S. Tsirkin

vhost: better variable name in logging

2010-12-09T14:00:10+00:00

We really store a page offset in write_address, so rename it write_page to avoid confusion. Signed-off-by: Jason Wang Signed-off-by: Michael S. Tsirkin

vhost: correctly set bits of dirty pages

2010-12-09T13:39:17+00:00

Fix two bugs in dirty page logging: When counting pages we should increase address by 1 instead of VHOST_PAGE_SIZE. Make log_write() correctly process requests that cross pages with write_address not starting at page boundary. Reported-by: Jason Wang Signed-off-by: Michael S. Tsirkin

vhost: remove unused include

2010-12-09T13:39:13+00:00

vhost.c does not need to know about sockets, don't include sock.h Signed-off-by: Michael S. Tsirkin

vhost: get/put_user -> get/put_user

2010-11-04T11:22:12+00:00

We do access_ok checks on all ring values on an ioctl, so we don't need to redo them on each access. Signed-off-by: Michael S. Tsirkin

vhost: copy_to_user -> __copy_to_user

2010-11-04T11:22:11+00:00

We do access_ok checks at setup time, so we don't need to redo them on each access. Signed-off-by: Michael S. Tsirkin
