Same as with already do with the file operations: keep them in .rodata and prevents people from doing runtime patching. Signed-off-by: Christoph Hellwig Cc: Steven French Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

Revert "[PATCH] kthread: update loop.c to use kthread"

2006-06-26T18:55:42+00:00

This reverts commit c7b2eff059fcc2d1b7085ee3d84b79fd657a537b. Hugh Dickins explains: "It seems too little tested: "losetup -d /dev/loop0" fails with EINVAL because nothing sets lo_thread; but even when you patch loop_thread() to set lo->lo_thread = current, it can't survive more than a few dozen iterations of the loop below (with a tmpfs mounted on /tst): j=0 cp /dev/zero /tst while : do let j=j+1 echo "Doing pass $j" losetup /dev/loop0 /tst/zero mkfs -t ext2 -b 1024 /dev/loop0 >/dev/null 2>&1 mount -t ext2 /dev/loop0 /mnt umount /mnt losetup -d /dev/loop0 done it collapses with failed ioctl then BUG_ON(!bio). I think the original lo_done completion was more subtle and safe than the kthread conversion has allowed for." Signed-off-by: Linus Torvalds

[PATCH] drivers/block/loop.c: don't return garbage if LOOP_SET_STATUS not called

2006-06-23T14:43:09+00:00

While writing a version of losetup, I ran into the problem that the loop device was returning total garbage. It turns out the problem was that this losetup was only issuing the LOOP_SET_FD ioctl and not issuing a subsequent LOOP_SET_STATUS ioctl. This losetup didn't have any special status to set, so it left out the call. The deeper cause is that loop_set_fd sets the transfer function to NULL, which causes no transfer to happen lo_do_transfer. This patch fixes the problem by setting transfer to transfer_none in loop_set_fd. Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
