ext4: calculate journal credits correctly
This fixes a 2.6.27 regression which was introduced in commit a02908f1. We weren't passing the chunk parameter down to the two subections, ext4_indirect_trans_blocks() and ext4_ext_index_trans_blocks(), with the result that massively overestimate the amount of credits needed by ext4_da_writepages, especially in the non-extents case. This causes failures especially on /boot partitions, which tend to be small and non-extent using since GRUB doesn't handle extents. This patch fixes the bug reported by Joseph Fannin at: http://bugzilla.kernel.org/show_bug.cgi?id=11964 Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
