Hi, is it possible to do this operation faster? I am going over 35k data entries and this takes quite some time. for(cnt in 2:length(sdata$date)) { if(sdata$value[cnt] < sdata$value[cnt - 1]) { sdata$ddtd[cnt] <- sdata$ddtd[cnt - 1] + sdata$value[cnt - 1] - sdata$value[cnt] } else sdata$ddtd[cnt] <- 0 } return(sdata) Thank you, Benjamin

Hello, the following series of patches fixes some issues with OCFS2 quotas. The first patch modifies VFS quota locking, the next patch uses the fact to simplify OCFS2 quota locking and solves a few deadlock issues. The third and the fourth patches fix another possible deadlocks in OCFS2 quota code and the last patch is a minor cleanup. Honza

Now when I am calling "@cnt.inspect" on object it gives me output as follows:- ----output---- [#"3"}>] ----------- Now in aboove output the number between double quotes (3) which is of my interest & I want to display it. How to do that? Actually this is my method:- =...

Not sure if this is a bug, so posting here first. If I run: ?? cnt <- 0L ?? while (TRUE) { ? ? ?? cnt <- cnt + 1L ? ? ?? p <- pipe("echo /dev/stdin > /dev/null", open = "w") ? ? ?? writeLines("foobar", p) ? ? ?? tryCatch(close(p), error = function(e) { print(cnt); stop(e)}) ?? } then once cnt gets to around 650, it...

vhost checked the counter within the refcnt before decrementing. It really wanted to know that it is the one that has the last reference, as a way to batch freeing resources a bit more efficiently. Note: we only let refcount go to 0 on device release. This works well but we now access the ref counter twice so there's a race: all users...

Hi Hal, > As we had briefly mentioned on IRC, one way of forming this 'stack', and its associated 'cnt' variable, is to use dynamic stack allocation. I hadn't really reached a decision on the mechanics yet. However, your suggestion while it can work within the current abilities of the IR, has the disadvantage that it is using an extra stack slot for the link pointer. I think if we are going...
