Package: logtail Version: 1.2.52 Severity: normal Tags: patch Hi, When a logfile is rotated, logtail misses the lines logged between the last logtail run and the logfile rotation. The attached patch allows to set an alternate logfile that logtail tries to use as the old logfile if the inode has changed. It can be used as: logtail -f /var/log/syslog -a /var/log/syslog.1 (Please note that this

Hi Xiantao, I general I think the code in this patch is fine. I have a couple of nit-picking comments: > + if (target_mask&0x1) { The formatting here isn't quite what most of the kernel does. It would be better if you added spaces so it's a little easier to read, ie: if (target_mask & 0x1) { > + p = &__per_cpu_idtrs[cpu][0][0]; > + for (i = IA64_TR_ALLOC_BASE;
