We're removing from XFS the ability to perform no-allocation file creation. This was added years ago because some customer of SGI demanded that we still be able to create (empty?) files with zero free blocks remaining so long as there were free inodes and space in existing directory blocks. This came at an unacceptable risk of ENOSPC'ing midway through a transaction and shutting down the fs, so we're removing it for the create case having changed our minds 20 years later. However, some tests fail as a result, so fix them to be more flexible about not failing when a dir/file creation fails due to ENOSPC. Signed-off-by: Darrick J.
