Subject: Fix: lttng UST and kernel consumer: fix ret vs errno mixup
X-Git-Url: http://git.efficios.com/?a=commitdiff_plain;h=6bf73bf53464ad309fcf7f02a4dc397d280b81f8;hp=6bf73bf53464ad309fcf7f02a4dc397d280b81f8;p=lttng-tools.git

Fix: lttng UST and kernel consumer: fix ret vs errno mixup

- errno should be set to -ret (not the opposite!)
  The main effect is that the perror errors were meaningless.

- errno should always be compared with positive values.
  This was also causing consumerd error handling mistakes.
