vfs: don't use BKL in default_llseek There are currently 191 users of default_llseek. Nine of these are in device drivers that use the big kernel lock. None of these ever touch file->f_pos outside of llseek or file_pos_write. Consequently, we never rely on the BKL in the default_llseek function and can replace that with i_mutex, which is also used in generic_file_llseek. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
