Subject: [PATCH] journal: return better error for empty files
|
|
|
|
|
|
|
|
|
|
When reading stuff, we should only return EIO when an actual read error
|
|
|
|
|
occured, not when we don't like the data for whatever reason.
|
|
|
|
|
|
|
|
|
|
We already return ENODATA for all other kinds of file truncation, hence
|
|
|
|
|
do the same for the most obvious kind, so that callers know what ENODATA
|
|
|
|
|
means.
|
|
|
|
|
|
|
|
|
|
