[0/4] exfat: Fixes for ENAMETOOLONG error handling

Message

Hi,

this is a series for fixing the error code of rename syscall as well
as cleanup / suppress the superfluous error messages.

As an LTP test case reported, exfat returns the inconsistent error
code for the case of renaming oversized file names:
  https://bugzilla.suse.com/show_bug.cgi?id=1201725
The first patch fixes this inconsistency.

The second patch is just for correcting the definitions as bit flags,
and the remaining two patches are for suppressing the error message
that can be triggered too easily to debug messages.


thanks,

Takashi
