This patch adds the ability to mount filesystems via an embedded fstab or via the kernel command line. When using the kernel command-line, the following format is required: 'kinit_mount=<fs_name>;<fs_dir>;<fs_type>;<fs_opts>' Multiple mount options can be specified; they are evaluated in the order they appear in the command-line.

A bunch of fixes (memory leaks, NULL pointer dereferences and devices hanging in busy state) to sanitize error handling during mount sequence. This is on top of for-linus + slyfox''s double-free fix. Thanks, Ilya Ilya Dryomov (5): Btrfs: fix memory leak in btrfs_parse_early_options() Btrfs: fix subvol_name leak on error in btrfs_mount() Btrfs: avoid null dereference and leaks

This patch series allows user-specified mount commands to be sent in via kernel command line ("kinit_mount=...") or via an embedded /etc/fstab file. The first patch is a cleanup of a patch sent last November by San Mehat (http://web.archiveorange.com/archive/v/EazJNBMORV2U7E0coh5h); the next two are small improvements or bug fixes.

hello, Chris In the next several months, I will have a lot of spare time. I will be happy if you assign some work to me. I have learn linux kernel for years but only fix a few small bugs in IP stack. In the past few months, I read some EXT4/VFS codes. I began reading source of btrfs ten days ago and have read it twice now. Regards YZ

Hi, this series start to implement some of the changes needed to support d-i-b 2.0; normal VM distro builds seem to work correctly, ramdisk builds are still broken and require more efforts. Thanks, Pino Toscano (5): dib: implement get_image_element_array stuff dib: export IMAGE_BLOCK_DEVICE_WITHOUT_PART dib: extract get_required_tool out of require_tool dib: require a Python interpreter
