2009-05-12block: fix the bio_vec array index out-of-bounds testKazuhisa Ichikawa
Current bio_vec array index out-of-bounds test within __end_that_request_first() does not seem correct. It checks bio->bi_idx against bio->bi_vcnt, but the subsequent code uses idx (which is, bio->bi_idx + next_idx) as the array index into bio_vec array. This means that the test really make sense only at the first iteration of !(nr_bytes >=bio->bi_size) case (when next_idx == zero). Fix this by replacing bio->bi_idx with idx. (This patch applies to 2.6.30-rc4.) Signed-off-by: Kazuhisa Ichikawa <ki@epsilou.com> Signed-off-by: Jens Axboe <jens.axboe@oracle.com>

2009-05-09V4L/DVB (11662): v4l2-ioctl: Clear buffer type specific trailing fields/paddingTrent Piepho
Some ioctls have structs that are a different size depending on what type of buffer is being used. If the buffer type leaves a field unused or has padding space at the end, this space should be zeroed out. The problems with S_FMT and REQBUFS were original identified and patched by Marton Nemeth <nm127@freemail.hu>.

2009-05-09V4L/DVB (11661): v4l2-ioctl: Check buffer types using g_fmt instead of try_fmtTrent Piepho
For a number of different ioctls, the v4l2-ioctl code checks that the passed buffer type is supported by the driver. It did this by checking that the driver defined a method for the try_fmt handler for that buffer type. However, try_fmt is optional and a driver might not provide it even though it does support that type. So use g_fmt instead, since that isn't optional. This should fix a problem with VBI capture with saa7146. Signed-off-by: Trent Piepho <xyzzy@speakeasy.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2009-05-09V4L/DVB (11660): zoran: fix bug when enumerating format -1Trent Piepho
If someone requests a format at fmt->index == (unsigned)-1 and the first format in the array doesn't have the requested type then num will still be -1 when it's compared to fmt->index and there will appear to be a match. Restructure the loop so this can't happen. It's simpler this way too. The unnecessary check for (unsigned)fmt->index < 0 found by Roel Kluin <roel.kluin@gmail.com> is removed this way too.

2009-05-09V4L/DVB (11575): uvcvideo: fix uvc resume failedMing Lei
Now urb buffers is not freed before suspend, so uvc_alloc_urb_buffers should return packet counts allocated originally during uvc resume, instead of zero. This version uses round down to return packet counts on Linus' suggestions, or else may lead to buffer destructed if packet size is changed before calling uvc_alloc_urb_buffers() in this kind of case.

2009-05-09New helper: deactivate_locked_super()Al Viro
Does equivalent of up_write(&s->s_umount); deactivate_super(s); However, it does not does not unlock it until it's all over. As the result, it's safe to use to dispose of new superblock on ->get_sb() failure exits - nobody will see the sucker until it's all over. Equivalent using up_write/deactivate_super is safe for that purpose if superblock is either safe to use or has NULL ->s_root when we unlock. Normally filesystems take the required precautions, but a) we do have bugs in that area in some of them. b) up_write/deactivate_super sequence is extremely common, so the helper makes sense anyway.

2009-05-09reiserfs: fixup xattr_root cachingJeff Mahoney
The xattr_root caching was broken from my previous patch set. It wouldn't cause corruption, but could cause decreased performance due to allocating a larger chunk of the journal (~ 27 blocks) than it would actually use. This patch loads the xattr root dentry at xattr initialization and creates it on-demand. Since we're using the cached dentry, there's no point in keeping lookup_or_create_dir around, so that's removed.

2009-05-09reiserfs: Expand i_mutex to enclose lookup_one_lenJeff Mahoney
2.6.30-rc3 introduced some sanity checks in the VFS code to avoid NFS bugs by ensuring that lookup_one_len is always called under i_mutex. This patch expands the i_mutex locking to enclose lookup_one_len. This was always required, but not not enforced in the reiserfs code since it does locking around the xattr interactions with the xattr_sem. This is obvious enough, and it survived an overnight 50 thread ACL test. Signed-off-by: Jeff Mahoney <jeffm@suse.com> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
