Sage Weil	a3ad98a3ee	librbd: hide ENOENT on discard ... AioZero, Truncate, and Remove are only used by discard and resize operations where ENOENT can be safely ignored. If that changes in the future, we'll need to move the enoent flag setting into discard explicitly. Fixes: #2958 Signed-off-by: Sage Weil <sage@inktank.com>	2012-08-17 12:10:05 -07:00
Josh Durgin	90dc565022	librbd: implement read/write from parent images ... Put the completion handling logic into new subclases of librbd::AioRequest, so the caching/non-caching paths can share logic. These AioRequests replace AioBlockCompletion as representing the I/O to a single object in an RBD image. Signed-off-by: Josh Durgin <josh.durgin@inktank.com>	2012-08-03 18:48:53 -07:00
