All, I've devised a way to toss a coin three times and record the number of heads, then use the table command to summarize the number of time 0, 1, 2, or 3 heads were obtained. n <- 100 x <- sample(c("H","T"),3*n,replace=TRUE) dim(x) <- c(3,n) num_heads <- apply(x,2,function(x) sum(x=="H")) table(num_heads)/n What I'd like to do next is run this code 10 times, and gather the results in a matrix with 10 rows and 4 columns, where the first row records the output of the first run of the above code, the second row records the second...

qdev->monitors_config->max_allowed is effectively set by the qxl.num_heads module parameter, stored in the qxl_num_crtc variable. Lets get rid of the indirection and use the variable qxl_num_crtc directly. The kernel doesn't need to dereference pointers each time it needs the value, and when reading the code you don't have to trace where and why qdev->monitor...

This is a first draft of a subvolume quota implementation. It is possible to limit subvolumes and any group of subvolumes and also to track the amount of space that will get freed when deleting snapshots. The current version is functionally incomplete, with the main missing feature being the initial scan and rescan of an existing filesystem. I put some effort into writing an introduction into
