Wong" , Luis Chamberlain From: Christophe JAILLET commit 132bf6723749f7219c399831eeb286dbbb985429 upstream. In this function, once 'buf' has been allocated, we unconditionally return 0. However, 'error' is set to some error codes in several error handling paths. Before commit 232b51948b99 ("xfs: simplify the xfs_getbmap interface") this was not an issue because all error paths were returning directly, but now that some cleanup at the end may be needed, we must propagate the error code.
