The buffer passed to btrfs_ioctl_tree_search* functions have to be at least sizeof(struct btrfs_ioctl_search_header). If this is not the case then the ioctl should return -EOVERFLOW and set the uarg->buf_size to the minimum required size. Currently btrfs_ioctl_tree_search_v2 would return an -EOVERFLOW error with ->buf_size being set to the value passed by user space. Fix this by removing the size check and relying on search_ioctl, which already includes it and correctly sets buf_size.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
