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

Hello, Happy New Year! These patches make syslinux/linux support ext2/3/4, and it doesn't require the root privilege, I'd like to add a separate e2fs/syslinux, if that is more appropriate, it should be easy to do that. I put these patches on github so that you can easily get them in case you'd like to test them. (The repo's name is sys_tmp, which avoids confusing others, I will

This set of patches add some support for sector size >512. Currently it fixes extlinux, MBR for GPT and ext partitions. Other code is unaffected. This set of patches has been tested on a read Dell machine running a beta firmware.
