Jan Blunck 866707fc27 Documentation/filesystems/Locking: update documentation on llseek() wrt BKL 
The inode's i_size is not protected by the big kernel lock.  Therefore it
does not make sense to recommend taking the BKL in filesystems llseek
operations.  Instead it should use the inode's mutex or use just use
i_size_read() instead.  Add a note that this is not protecting
file->f_pos.
