Hi folks,
I noticed I'm able to apply every one of the 46 bcache patches, from the
3.15 & 3.17 git pulls Kent submitted to Jens, to my vanilla 3.14.23
kernel, without any fuziness. See bottom of this mail for output from
applying the 46 in order.
I see all of them only touch files under drivers/md/bcache, and
occasionally include/trace/events/bcache.h. So all bcache files.
The result also builds fine without any warnings or errors.
Obviously there's no guarantees in life, but do others here think what
I'm doing here looks reasonably safe, or is there a big risk that bcache
will eat my data?
thanks,
Eddie
