7e9ec50b0535 "tools/libxl: Adjust datacopiers POLLHUP handling when the fd is also readable" has been reverted by the application of what was 1/3 of v1 of this mini-series.
(Sorry about the odd reference in the commit message to `later in this mail', which was a reference to `Avoid [theoretical] eof/POLLHUP race' and ought to have just read `later'.) These are the remaining two patches: [PATCH 1/2] libxl: datacopier: Avoid eof/POLLHUP race This was 3/3 and was described as "theoretical" but with a test patch Roger has been able to reproduce it and verify that this patch fixes the problem. This bug is still (I think) quite unlikely, but this patch is a IMO candidate for backport. [PATCH 2/2] libxl: Cope with pipes which signal POLLHUP|POLLIN on An earlier (wrong, I now think) approach to this was 2/3 of the previous series. I have removed Ian Campbell's ack. It would be good to know whether this revised version actually fixes the bug that 7e9ec50b0535 was aimed at. Thanks, Ian. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xen.org http://lists.xen.org/xen-devel
