configfs: Fix potential NULL d_inode dereference

2015-02-20T09:56:43+00:00

Code that does this: if (!(d_unhashed(dentry) && dentry->d_inode)) { ... simple_unlink(parent->d_inode, dentry); } is broken because: !(d_unhashed(dentry) && dentry->d_inode) is equivalent to: !d_unhashed(dentry) || !dentry->d_inode so it is possible to get into simple_unlink() with dentry->d_inode == NULL. simple_unlink(), however, assumes dentry->d_inode cannot be NULL. I think that what was meant is this: !d_unhashed(dentry) && dentry->d_inode and that the logical-not operator or the final close-bracket was misplaced.

configfs: configfs_create() init callback is never NULL and it never fails

... so make it return void and drop the check for it being non-NULL Signed-off-by: Al Viro

fs: remove mapping->backing_dev_info

2015-01-20T21:03:05+00:00

Now that we never use the backing_dev_info pointer in struct address_space we can simply remove it and save 4 to 8 bytes in every inode. Signed-off-by: Christoph Hellwig Acked-by: Ryusuke Konishi Reviewed-by: Tejun Heo Reviewed-by: Jan Kara Signed-off-by: Jens Axboe

fs: introduce f_op->mmap_capabilities for nommu mmap support

2015-01-20T21:02:58+00:00

Since "BDI: Provide backing device capability information [try #3]" the backing_dev_info structure also provides flags for the kind of mmap operation available in a nommu environment, which is entirely unrelated to it's original purpose. Introduce a new nommu-only file operation to provide this information to the nommu mmap code instead. Splitting this from the backing_dev_info structure allows to remove lots of backing_dev_info instance that aren't otherwise needed, and entirely gets rid of the concept of providing a backing_dev_info for a character device. It also removes the need for the mtd_inodefs filesystem. Signed-off-by: Christoph Hellwig Reviewed-by: Tejun Heo Acked-by: Brian Norris Signed-off-by: Jens Axboe
