[PATCH v2] Btrfs: fix btrfs_decompress_buf2page()

From: Omar Sandoval If btrfs_decompress_buf2page() is handed a bio with its page in the middle of the working buffer, then we adjust the offset into the working buffer. After we copy into the bio, we advance the iterator by the number of bytes we copied. Then, we have some logic

This is not a Btrfs problem yet. Syslinux isn't even getting the kernel and initramfs loaded, otherwise you'd get a failure during boot. But instead you're at the bootloader still. One thing to realize is that syslinux only finds kernels and initramfs on the local file system. So assuming this

proper syslinux settings for ext4 boot, dm-crypt + btrfs subvol root?

Greetings, I'm trying to utilize btrfs subvols to allow me to boot separate distros without having to create so many partitions. I'm on Arch Linux and not finding the wiki super helpful with specifics on dm-crypt/luks and btrfs. Requested info: $ uname -a Linux arch_zbook 4.9.8-1-ARCH #1 SMP

Help understanding autodefrag details

Hi, As I have been reading btrfs whitepaper it speaks about autodefrag in very generic terms - once random write in the file is detected it is put in the queue to be defragmented. Yet I could not find any specifics about this process described anywhere. My use case is databases and as such
