[dm-devel] dm-cache: dirty state of blocks in writethrough mode

[Vijarnia, Anil]

Hello,

In Documentation/cache.txt, section 'Updating on-disk metadata' mentions that "If the system crashes all cache blocks will be assumed dirty when restarted".

I am assuming that the above line is relevant for writeback mode only, and in writethrough mode the cache will always be coherent after a crash.

Can someone confirm/reject this assumption?



Thanks
