Can you please give your ideas about logic to catch abuse of live ranges?

Hi, I wanted to create a new btrfs fs for my backups. When trying to mkfs.btrfs for that device, I''m getting "error checking /dev/loop2 mount status" With strace I see where the problem is: lstat("/dev/disk/by-id/ata-INTEL_SSDSA2M160G2GC_CVPO939201JX160AGN-par", 0x7fffa30b3cf0) = -1 ENOENT (No such file or directory) The problem is there is something missing at the end of the link, should be something like &quo...

How do I mount a partition that is in an image file? I have a file called centos.img that has 3 partitions in the file. I need to copy data to the third partition on that image file. I have seen things about a loop back device (which is fine) but then it talked about an offset parameter and I dont know what that is or more importantly what number to use. I hope I'm on the right track. How

Hi Folks, Let's keep this optimization alive. To summarize: several folks voiced general support, but with questions about why existing optimizations do not already catch this case. Deep dive by Wei Mi showed that the optimization is most likely not a clean-up of LSR sloppiness, but something new. Follow-up by myself confirmed that the redundancy eliminated the LoopExitValues pass exists in

Hi! I recently tried to mount a filesystem in RAID1 mode using loopback devices. I followed the instructions at [1]. Here''s exactly what I''ve done: $ dd if=/dev/zero of=raid1_0.img bs=1M count=500 $ dd if=/dev/zero of=raid1_1.img bs=1M count=500 $ mkfs.btrfs -m raid1 -d raid1 raid1_0.img raid1_1.img $ losetup /dev/loop0 raid1_0.img $ losetup /dev/loop1 raid1_1.img $ mount -t

Hello list, I would like to share a little problem with you : I've lost an 5Gb partition in an installation of Ututo GNU/Linux. It seems that the installation script does not took care of my /home and it tried of format it. When I saw that my old sda8 partition was being formatted as ext3 (fast format) I immediately, hard-restart my computer. After a run level 1 restart, I discovered that it

Continuing on with my earlier post . . . after looking through code of JBD, is the following perhaps the difference in why the md5 values differ; When a journalled filesystem that uses jbd is mounted the journal b_count is incremented by one? *EVEN* if the volume was mounted read only, this b_count is still increased by one? curious as ever! lt __________________________________ Do you

...'s inter-iteration pre attempts. Staring at this case for a second, my money is on the following happening. 1. PRE starts by asking if the value of step[i] where i == 0 is fully available in all preds 2. PHITransaddr get it as part of memdep, and inside of those preds (which are in loop 1, not loop2), using it's magical powers, gives an answer about step[i] (note, not step[0]) instead. This answer may even be valid in the loop. The problem may even be related to the fact that the loops both iterate the same way (so it thinks step[i] is valid in both, even though the i's are differen...
