Not yet, I'll get one up for the next version of the patchset and I
have done some page cache vs inode cache balance testing. That,
FWIW, is not looking good - the vanilla 5.3-rc3 kernel is unable to
maintain a balanced page cache/inode cache working set under steady
state tarball-extraction workloads. Memory reclaim looks to be have
been completely borked from a system balance perspective since I
last looked at it maybe a year ago....

Cheers,

Dave.
