inform aiori interface about RADOS backend
stubbed out aiori backend for rados
additions to get RADOS backend compiling/linking
first cut at rados create/open patha
make sure to return RADOS oid on open/create
implement rados xfer path for WRITE
refactor + implement getfilesize and close
remember to use read_op interface for stat
implement RADOS delete function
don't error in RADOS_Delete for now
implement RADOS set_version
handle open/create flags appropriately
cleanup RADOS error handling
implement read/readcheck/writecheck for RADOS
rados doesn't support directio
implement unsupported aiori ops for RADOS
implement RADOS access call
define rados types if no rados support
This commit makes changes to the AIORI backends to add support for
abstacting statfs, mkdir, rmdir, stat, and access. These new
abstractions are used by a modified mdtest. Some changes:
- Require C99. Its 2017 and most compilers now support C11. The
benefits of using C99 include subobject naming (for aiori backend
structs), and fixed size integers (uint64_t). There is no reason to
use the non-standard long long type.
- Moved some of the aiori code into aiori.c so it can be used by both
mdtest and ior.
- Code cleanup of mdtest. This is mostly due to the usage of the IOR
backends rather than a mess of #if code.
