Linus,
To save you from some merge conflicts, I rebased this readahead patchset
to 2.6.22-git5.
The following patches are based on yesterday's discussions, compiled and
tested OK.
smaller file_ra_state:
[PATCH 1/8] compacting file_ra_state
[PATCH 2/8] mmap read-around simplification
[PATCH 3/8] combine file_ra_state.prev_index/prev_offset into prev_pos
code cleanups:
[PATCH 4/8] trivial filemap.c cleanups
[PATCH 5/8] remove several readahead macros
[PATCH 6/8] remove the limit max_sectors_kb imposed on max_readahead_kb
support of interleaved reads:
[PATCH 7/8] introduce radix_tree_scan_hole()
[PATCH 8/8] basic support of interleaved reads
