| |
I've just uploaded a new version of the radix-tree pagecache patch to kernel.org. This version should fix the OOPSens in the last version by beeing more carefull with the page->flags handling.
I have tested the 2.4 version under varying loads for about 20 hours now and it seems stabel, the 2.5 version just got a compiles & boots, I don't really trust 2.5 in this stage..
The only real difference between the two patches is the use of Ingo Molnar's mempool interface in the 2.5 version, this is needed to not deadlock under extreme loads. If you want to have this with a 2.4-based kernel you have to get a mempool backport from somewhere and just copy lib/radix-tree.c from the 2.5 radix pagecache patch.
The patches are located at:

Please give them some beating so I can declare them ready for 2.5 when Linus is back from vacation..
