fs: Remove ext3 filesystem driver

2015-07-23T18:59:40+00:00

The functionality of ext3 is fully supported by ext4 driver. Major distributions (SUSE, RedHat) already use ext4 driver to handle ext3 filesystems for quite some time. There is some ugliness in mm resulting from jbd cleaning buffers in a dirty page without cleaning page dirty bit and also support for buffer bouncing in the block layer when stable pages are required is there only because of jbd. So let's remove the ext3 driver. This saves us some 28k lines of duplicated code. Acked-by: Theodore Ts'o Signed-off-by: Jan Kara

ext3: ext3_bread usage audit

2012-10-09T21:21:42+00:00

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. Signed-off-by: Carlos Maiolino Signed-off-by: Jan Kara
