similar to: Determine if a given fs is a btrfs fs

It seems that the BTRFS_IOC_CLONE ioctl fails when trying to do a cross-subvolume clone of a file. Chris Mason suggested in the past ([1]) that this should be possible. Am I missing something?

Glück Auf! I know its been discussed more then ones, but as a user I really would like to see the patch for allowing this in the kernel. Some users tested this patch successfully for weeks or months in 2 or 3 kernel versions since then, true? I''d say by creating a snapshot, it''s nothing else in the end. More then one file or tree sharing the same data on disc, or am I wrong?

Hi, We are currently porting our application to Windows 64 bits (amd64), and we are getting regressions from 32 bits relatively to LLVM 3.0's ability to get traversed by "foreign" Visual Studio C++ exceptions. That is, there is a crash when C++ exceptions which are thrown from Visual Studio code, are unwinding through LLVM code before being eventually catch by other Visual Studio

Hello, My hoster updated its kernel packages... It contained some old problems that should have been fixed. My servers have now a wonderful 2.6.21.5 kernel + grsec running. Both are running Debian 4.0 (stable release). mx:/etc/shorewall# iptables --version iptables v1.3.6 mx:/etc/shorewall# uname -a Linux mx.network-hosting.com 2.6.21.5-grsec-xxxx-grs-ipv4-32 #1 SMP Fri Jul 27 17:18:23 CEST

Consider the examble below: plot(0,0) legend(0,0,c("Hello!","Hi!"),pch=1:2,lty=1:2,trace=T) It gives the following trace: > plot(0,0) > legend(0,0,c("Hello!","Hi!"),pch=1:2,lty=1:2,trace=T) xchar= 0.05178 ;

So we might want to delay upstreaming until this lands.

Hi, just for your information and maybe for some help: with 5.1rc1 and SVM enabled i see the following backtrace [1] when the nouveau card (reverse prime) goes to sleep, for now i have papered over with [2] which leaves me with userspace hangs. Any pointers where to look for the actual culprit? PS: Card is: nouveau 0000:01:00.0: NVIDIA GP106 (136000a1) Greetings, Tobias [1]: BUG: unable

Dear R-gurus, We are planning an experiment to test if plants produced by selfing are less fit than those produced by outcrossing. We have plants from three different alpine valleys, picked randomly among all the possible valleys. In each valley, we have a number of individuals, also picked at random. seeds from this individuals were brought back to the green house and sawned. when they
