Subject: [f2fs-dev] [PATCH 0/2] f2fs-tools: add 'copy' command to f2fs_io
Date: Fri,  4 Oct 2019 15:43:15 -0700
Message-ID: <20191004224317.153566-1-ebiggers@kernel.org> (raw)

Add a copy command to f2fs_io, to allow testing direct I/O writes where
the source page is from a different file (mmap) or an internal kernel
page (sendfile).  It could be useful for other tests in the future too.

  f2fs_io: add helper functions for handling errors
