| H A D | dm-stripe.c | 9966afaf Sat Jun 03 02:37:57 CDT 2017 Christoph Hellwig <hch@lst.de> dm: fix REQ_RAHEAD handling
A few (but not all) dm targets use a special EWOULDBLOCK error code for
failing REQ_RAHEAD requests that fail due to a lack of available resources.
But no one else knows about this magic code, and lower level drivers also
don't generate it when failing read-ahead requests for similar reasons.
So remove this special casing and ignore all additional error handling for
REQ_RAHEAD - if this was a real underlying error we'd get a normal read
once the real read comes in.
