[PATCH 5/16] fs/btrfs: Use available error codes

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

 



From: Julia Lawall <julia@xxxxxxx>

Error codes are stored in ret, but the return value is always 0.  Return
ret instead.

The semantic match that finds this problem is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>
@r@
local idexpression x;
constant C;
@@

if (...) { ...
  x = -C
  ... when != x
(
  return <+...x...+>;
|
  return NULL;
|
  return;
|
* return ...;
)
}
// </smpl>

Signed-off-by: Julia Lawall <julia@xxxxxxx>

This changes the semantics and has not been tested.
