As far as I remember at OLS we decided to implement per-zone RLU lists and reuse the lru lock as well. This will remove all the problems with per-container lists inconsistency. Separate limits for RSS and RSS+pagecache are also a must. BTW, if you send smb. else's patches you may include a 'From: xxx' line into the letter to address the original author. > At OLS, the resource management BOF, it was discussed that we need to manage > RSS and unmapped page cache together.
