This patch is a counterpart to the CIFS patch posted yesterday. I believe either patch will fix the problem seen in do_sendfile since the smaller s_maxbytes value for the two superblocks is used there. get_sb_pseudo sets s_maxbytes to ~0ULL, which becomes negative when cast to a signed value. Fix it to use MAX_LFS_FILESIZE which casts properly to a positive signed value.
