- This is a simple debugfs interface to inject MCEs and test different
- aspects of the MCE handling code.
- WARNING: Do not even assume this interface is staying stable!

- bool "Correctable Errors Collector"
- depends on X86_MCE && MEMORY_FAILURE && DEBUG_FS
- ---help---
- This is a small cache which collects correctable memory errors per 4K
- page PFN and counts their repeated occurrence. Once the counter for a
- PFN overflows, we try to soft-offline that page as we take it to mean
- that it has reached a relatively high error count and would probably
- be best if we don't use it anymore.
- Bear in mind that this is absolutely useless if your platform doesn't
- have ECC DIMMs and doesn't have DRAM ECC checking enabled in the BIOS.
