balance_leaf() in fs/reiserfs/do_balan.c
Example picked totally at random:
set_le_ih_k_offset(ih,
le_ih_k_offset(ih) +
(tb->
lbytes <<
(is_indirect_le_ih
(ih) ? tb->tb_sb->
s_blocksize_bits -
UNFM_P_SHIFT :
0)));
See how everything is nicely aligned to 80 cols?
Generally, don't look at this function after having a good lunch you want
to keep. You have been warned.
