Now that both native and compat ioctl syscalls are in the same file, a couple of simplifications can be made, bringing the implementation closer together: - do_vfs_ioctl(), ioctl_preallocate(), and compat_ioctl_preallocate() can become static, allowing the compiler to optimize better - slightly update the coding style for consistency between the functions. - rather than listing each command in two switch statements for the compat case, just call a single function that has all the common commands. As a side-effect, FS_IOC_RESVSP/FS_IOC_RESVSP64 are now available to x86 compat tasks, along with FS_IOC_RESVSP_32/FS_IOC_RESVSP64_32. This is harmless for i386 emulation, and can be considered a bugfix for x32 emulation, which never supported these in the past.
