xfs_is_valid_magicnum is not actually a generic function that checks for magic numbers, instead it checks only for superblock's one.

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.

Hi, i began to implement a common lookup function for SUSP and Rock Ridge entries: /* Obtain the payload bytes of all SUSP entries with a given signature. @param fs The data source from which to read CE blocks. @param dir_rec Memory containing the whole ISO 9660 directory record. @param sig Two characters of SUSP signature.

Hello, the following patches should get multidisk access working. The syntax accepted is the following: (hdx,y)/path/to/file where x is the disk number and start at 0 and the y is the partition number starting at 1. So (hd0,1) is the first partition of the first disk. the other accepted syntax is using MBR's 32 bits disk signature so for example: (mbr:0x12345678,2)/foo/bar would address

So last week I was wondering if XFS was still working -- even with its last on-disk structure changes -- and it _suprisingly_ worked as expected. Right, now I can finally get rid of GRUB and use Syslinux to boot my Linux on EFI from a rootfs with xfs. Shit, I have two partitions (the first one being the required ESP) so there is no way to access the other partitions since because Syslinux does not
