Convert jfs_ioctl over to not use the BKL. The only potential race I could see was with two ioctls in parallel changing the flags and losing the updates. Use the i_mutex to protect against this. Signed-off-by: NAndi Kleen <ak@suse.de> Signed-off-by: NDave Kleikamp <shaggy@linux.vnet.ibm.com>

struct user.u_ar0 is defined to contain a pointer offset on all architectures in which it is defined (all architectures which define an a.out format except SPARC.) However, it has a pointer type in the headers, which is pointless -- <asm/user.h> is not exported to userspace, and it just makes the code messy. Redefine the field as "unsigned long" (which is the same size as a pointer on all Linux architectures) and change the setting code to user offsetof() instead of hand-coded arithmetic.

Remove the old iget() call and the read_inode() superblock operation it uses as these are really obsolete, and the use of read_inode() does not produce proper error handling (no distinction between ENOMEM and EIO when marking an inode bad). Furthermore, this removes the temptation to use iget() to find an inode by number in a filesystem from code outside that filesystem. iget_locked() should be used instead. A new function is added in an earlier patch (iget_failed) that is to be called to mark an inode as bad, unlock it and release it should the get routine fail. Mark iget() and read_inode() as being obsolete and remove references to them from the documentation. Typically a filesystem will be modified such that the read_inode function becomes an internal iget function, for example the following: void thingyfs_read_inode(struct inode *inode) { ... } would be changed into something like: struct inode *thingyfs_iget(struct super_block *sp, unsigned long ino) { struct inode *inode; int ret; inode = iget_locked(sb, ino); if (!inode) return ERR_PTR(-ENOMEM); if (!(inode->i_state & I_NEW)) return inode; ... unlock_new_inode(inode); return inode; error: iget_failed(inode); return ERR_PTR(ret); } and then thingyfs_iget() would be called rather than iget(), for example: ret = -EINVAL; inode = iget(sb, ino); if (!inode || is_bad_inode(inode)) goto error; becomes: inode = thingyfs_iget(sb, ino); if (IS_ERR(inode)) { ret = PTR_ERR(inode); goto error; } Note that is_bad_inode() does not need to be called. The error returned by thingyfs_iget() should render it unnecessary.

Stop the HPPFS filesystem from using iget() and read_inode(). Provide an hppfs_iget(), and call that instead of iget(). hppfs_iget() then uses iget_locked() directly and returns a proper error code instead of an inode in the event of an error. hppfs_fill_sb_common() returns any error incurred when getting the root inode instead of EINVAL. Note that the contents of hppfs_kern.c need to be examined: (*) The HPPFS inode retains a pointer to the proc dentry it is shadowing, but whilst it does appear to retain a reference to it, it doesn't appear to destroy the reference if the inode goes away. (*) hppfs_iget() should perhaps subsume init_inode() and hppfs_read_inode(). (*) It would appear that all hppfs inodes are the same inode because iget() was being called with inode number 0, which forms the lookup key.

Rename old vfs_ioctl to do_ioctl, because the comment above it clearly indicates that it is an internal function not to be exported to modules; therefore it should have a more traditional do_XXX name. The new do_ioctl is exported in fs.h but not to modules. Rename the old do_ioctl to vfs_ioctl because the names vfs_XXX should preferably be reserved to callable VFS functions which modules may call, as many other vfs_XXX functions already do. Export the new vfs_ioctl to GPL modules so others can use it (including Unionfs and eCryptfs). Add DocBook for new vfs_ioctl.
