Subject: zonefs: Fix error message in zonefs_file_dio_append()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=88b170088ad2c3e27086fe35769aa49f8a512564;p=linux.git

zonefs: Fix error message in zonefs_file_dio_append()

Since the expected write location in a sequential file is always at the
end of the file (append write), when an invalid write append location is
detected in zonefs_file_dio_append(), print the invalid written location
instead of the expected write location.

Fixes: a608da3bd730 ("zonefs: Detect append writes at invalid locations")
