although that is generally not necessary. In particular it is not needed for conversion of data structures and for calling sys_ioctl or do_vfs_ioctl, which will get the BKL again if needed. Handlers doing more than those two have been moved out, so we can kill off the BKL from compat_sys_ioctl. This may significantly improve latencies with 32 bit applications, and it avoids a common scenario where a thread acquires the BKL twice.
