This patchset fixes some bugs of btrfs_ioctl(). Most of them (0004-0009) is
relative to write access permission.
In these patches, the last patch(0009) modified the original process of the
device
insertion，and made it follow the rule of the read-only filesystem. It might be
issuable, so mark it RFC.
We can pull this patchset from the URL
git://github.com/miaoxie/linux-btrfs.git readonly
Thanks
