Andrew,
The following readahead updates have been tested and should be OK for 2.6.23 :-)
smaller file_ra_state:
[PATCH 1/6] compacting file_ra_state
[PATCH 2/6] mmap read-around simplification
code cleanups:
[PATCH 3/6] remove several readahead macros
[PATCH 4/6] remove the limit max_sectors_kb imposed on max_readahead_kb
support of interleaved reads:
[PATCH 5/6] introduce radix_tree_scan_hole()
[PATCH 6/6] basic support of interleaved reads
The diffstat is
