Don't think this somekind of destructive discussion would lead to

This patch would apply to 2.4.18 + pending patches, I believe.
As for including these patchs into pending queue for 2.4.18, this is impossible

Attached is a speedup patch for 2.4.19-pre7 that should help your fsync
operations a little. (From Chris Mason).
Filesystem cannot do very much at this point unfortunatelly, it is ending up
waiting for disk to finish write operations.

Be careful with this approach. Apart from syncing other processes' dirty
