In 'core/fs/fs.c', 'fs.root' is set, but the 'iget_root' function pointer call might return a null pointer and we don't check for it. A symptom was that QEmu crashed as EIP landed outside of memory. - Shao /* start out in the root directory */ if (fs.fs_ops->iget_root) { fs.root = fs.fs_ops->iget_root(&fs);...

Hi hpa, I just added the generic path_lookup function for EXTLINUX. hpa, It changed a lot, so I want hear something from you. First , here is the main skeleton of the generic path_lookup function: > if (*name == '/') { > inode = this_fs->fs_ops->iget_root(); // The way to get the root > inode is different from different fs > while(*name == '/') > name++; > } else { > inode = this_inode; // pwd > } > parent = inode; > > while (*name) { > p =...

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

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

Carvalho <raphael.scarv at gmail.com> Change since v1: * Fix bug on dentry structure (thank you specification; btw, sarcasm), and consequently a bug on ufs_readdir. * Add readlink support (applied tests for symlinks whose destionation path were stored in blk pointers and the file itself). * Several improvements.
