Hi Mike, This is a follow up message. Did you have a chance to take a look at the latest patchset from April? Thanks! I can update the patch to be compatible with kernel 5.14. I would like to know if you still have interest in blk_interposer. -- Sergei Shtepa Veeam Software developer. -- dm-devel mailing list dm-devel@xxxxxxxxxx https://listman.redhat.com/mailman/listinfo/dm-devel
