Merge btrfs_read_adv and xfs_read_adv into a single generic function ext_read_adv and split ext_write_adv_offset out of ext_write_adv. Use those new functions in rewrite_boot_image and btrfs_install_file where it is actually hardcoded.

...if (xpread(devfd, syslinux_adv, adv_size, boot_image_len) != adv_size) return -1; return syslinux_validate_adv(syslinux_adv) ? 1 : 0; } boot_image_len for me is about 53 kb so it read after 53 kb after start of partition however comment on ext_read_adv state that 2kb is used. Also in ext_write_adv adv is written with a write_adv which use a file inside the filesystem so the first function looks wrong to me. Well, we are not corrupting XFS cause is a read and never a write but surely adv won't work for xfs code. I did not test it so I could be possible wrong. Frediano

Another week, *another* -pre. I'm really planning on this being the last one. The shortlog is appended below. Apart from a better fix for the "disabled menu entry" bug it's only documentation updates. Testing from the last -pre's has been pretty quiet, so as soon as Ady and Matt have tested this one and confirmed that the disabled entry bug is finally gone I'll do the

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.

Hello syslinux, Merry Christmas! These patches will make extlinux work with umounted ext2/3/4 filesystem, for example: $ extlinux -i /dev/sdXN or $ extlinux -i file_block Also it can work with something like: $ extlinux /dev/sdXN --reset-adv or $ extlinux file_block --reset-adv We don't use a new option (I planed to use "-d" but it is already in use), it will check whether the
