| * BKL-removal: Implement a compat_ioctl handler for JFSAndi Kleen2008-02-075-0/+27
| | | | | | | | | | | | | | | | The ioctls were already compatible except for the actual values so this was fairly easy to do. Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Dave Kleikamp <shaggy@linux.vnet.ibm.com>
| * BKL-removal: Use unlocked_ioctl for jfsAndi Kleen2008-02-074-7/+13
| | | | | | | | | | | | | | | | | | 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: Andi Kleen <ak@suse.de> Signed-off-by: Dave Kleikamp <shaggy@linux.vnet.ibm.com>

| * | ocfs2: Negotiate locking protocol versions.Joel Becker2008-02-0612-34/+288
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, when ocfs2 nodes connect via TCP, they advertise their compatibility level. If the versions do not match, two nodes cannot speak to each other and they disconnect. As a result, this provides no forward or backwards compatibility. This patch implements a simple protocol negotiation at the dlm level by introducing a major/minor version number scheme for entities that communicate. Specifically, o2dlm has a major/minor version for interaction with o2dlm on other nodes, and ocfs2 itself has a major/minor version for interacting with the filesystem on other nodes. This will allow rolling upgrades of ocfs2 clusters when changes to the locking or network protocols can be done in a backwards compatible manner. In those cases, only the minor number is changed and the negotatied protocol minor is returned from dlm join. In the far less likely event that a required protocol change makes backwards compatibility impossible, we simply bump the major number.

| | | | | | | | | | | | | | | | | | | | | | | | | | | It's possible that the caller of sysfs_remove_group messed up and passed in an attribute group that was not really registered to this kobject.

| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | The "whole_disk" attribute was not properly converted in the block device conversion earlier, and if the file is read, bad things can happen.

Removing them immediately from the f->dents list, however, screws up handling of f_pos within a directory -- because the offset is equivalent to the number of entries through the list we are, and the existence of deletion dirents served to provide 'placeholders' for unlinked entries. Now, 'rm -r' doesn't even manage to unlink everything in the directory. Revert to keeping 'deletion' dirents in the list, at least in memory even though we no longer write anything to the medium.

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.

* | | | iget: remove iget() and the read_inode() super op as being obsoleteDavid Howells2008-02-071-4/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.

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.
