Hello Tristan Ye,
This is a semi-automatic email about new static checker warnings.
The patch 53069d4e7695: "Ocfs2/move_extents: move/defrag extents
within a certain range." from May 25, 2011, leads to the following
Smatch complaint:
fs/ocfs2/move_extents.c:980 ocfs2_move_extents()
warn: variable dereferenced before check 'inode' (see line 978)
fs/ocfs2/move_extents.c
977 struct buffer_head *di_bh = NULL;
978 struct ocfs2_super *osb = OCFS2_SB(inode->i_sb);
^^^^^^^^^^^
Dereference.
979
980 if (!inode)
^^^^^^
Check.
981 return -ENOENT;
982
regards,
dan carpenter
