Julien Brunel bd1eb8818c GFS2: Use an IS_ERR test rather than a NULL test ... In case of error, the function gfs2_inode_lookup returns an ERR pointer, but never returns a NULL pointer. So a NULL test that necessarily comes after an IS_ERR test should be deleted, and a NULL test that may come after a call to this function should be strengthened by an IS_ERR test. The semantic match that finds this problem is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @match_bad_null_test@ expression x, E; statement S1,S2; @@ x = gfs2_inode_lookup(...) ... when != x = E * if (x != NULL) S1 else S2 // </smpl> Signed-off-by: Julien Brunel <brunel@diku.dk> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>		2008-09-05 14:19:44 +01:00
