Revision 8b2180b3bf0338625cab07da6543acb436df9c40 authored by Dave Chinner on 16 August 2016, 22:31:33 UTC, committed by Dave Chinner on 16 August 2016, 22:31:33 UTC
When we do DAX IO, we try to invalidate the entire page cache held on the file. This is incorrect as it will trash the entire mapping tree that now tracks dirty state in exceptional entries in the radix tree slots. What we are trying to do is remove cached pages (e.g from reads into holes) that sit in the radix tree over the range we are about to write to. Hence we should just limit the invalidation to the range we are about to overwrite.
