[PATCH][next] xattr: remove redundant check on variable err

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Curretly in function generic_listxattr the for_each_xattr_handler loop
checks err and will return out of the function if err is non-zero.
It's impossible for err to be non-zero at the end of the function where
err is checked again for a non-zero value. The final non-zero check is
therefore redundant and can be removed.
