https://bugzilla.kernel.org/show_bug.cgi?id=202441 Sami Farin (hvtaifwkbgefbaei@xxxxxxxxx) changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |hvtaifwkbgefbaei@xxxxxxxxx --- Comment #28 from Sami Farin (hvtaifwkbgefbaei@xxxxxxxxx) --- [....] When vfs_cache_pressure=0, the kernel will never reclaim dentries and inodes due to memory pressure and this can easily lead to out-of-memory conditions. [....] I wish that was true. I have it set to 0, and I have 32 GiB RAM of which 23 GiB free when doing the test using XFS filesystem: $ du -sh $ sleep 60 # (dentries forgotten, the next du takes a minute to run (SATA rust platter disk)) $ du -sh kernel 5.10.80.
