| |
I prefer to run stock kernels so I don't have as much experience with the -aa patches. However, I took a look at the relevant code in 2.4.22pre7aa1 and I believe my patch should help there as well. The writepage() and page rotation behaviour is similar to stock 2.4.22 though the inactive_list is per-classzone in -aa. I am less sure about the inode/dcache part though under -aa.
