2012-10-09	ext3: ext3_bread usage audit	Carlos Maiolino	1	-0/+19
	This is the ext3 version of the same patch applied to Ext4, where such goal is to audit the usage of ext3_bread() due a possible misinterpretion of its return value. Focused on directory blocks, a NULL value returned from ext3_bread() means a hole, which cannot exist into a directory inode. It can pass undetected after a fix in an uninitialized error variable. The (now) initialized variable into ext3_getblk() may lead to a zero'ed return value of ext3_bread() to its callers, which can make the caller do not detect the hole in the directory inode. This patch creates a new wrapper function ext3_dir_bread() which checks for holes properly, reports error, and returns EIO in that case.
