This has received stress testing (Crefi, w/ Cache_Inode::Cache_Size == 10000, Entries_Hwmark = 10000). |
|
Are these values after the fix applied? What were values before? |
|
@amitkumar50 sorry, these values are cache tuning parameters, which are sufficiently small to force (and I observed) frequent execution of evict_block(). |
