ext4_fallocate() was trying to acquire i_data_sem outside of jbd2_start_transaction/jbd2_journal_stop, which violates ext4's locking hierarchy. So we take i_mutex to prevent writes and truncates during the complete fallocate operation, and use ext4_get_block_wrap() which acquires and releases i_data_sem for each block allocation.

I added a nasty local variable shadowing bug to fuse in 2.6.24, with the result, that the 'default_permissions' mount option is basically ignored. How did this happen? - old err declaration in inner scope - new err getting declared in outer scope - 'return err' from inner scope getting removed - old declaration not being noticed -Wshadow would have saved us, but it doesn't seem practical for the kernel :( More testing would have also saved us :(( Signed-off-by: NMiklos Szeredi <mszeredi@suse.cz> Cc: <stable@kernel.org> Signed-off-by: NAndrew Morton <akpm@linux-foundation.org> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

Sorry for the noise, but here's the v3 of this compilation fix :) There are some places, which declare the char buf[...] on the stack to push it later into dprintk(). Since the dprintk sometimes (if the CONFIG_SYSCTL=n) becomes an empty do { } while (0) stub, these buffers cause gcc to produce appropriate warnings. Wrap these buffers with RPC_IFDEBUG macro, as Trond proposed, to compile them out when not needed. Signed-off-by: NPavel Emelyanov <xemul@openvz.org> Acked-by: NJ.

Noted by various people (Sam, Jeff, Roland..) Commit 58b7983d intended to remove the xfs "Makefile-linux-2.6" file, but it was mistakenly still left in the tree as a empty file, and would cause git to correctly complain about a tracked file being removed after a "make distclean" (which removes empty files as garbage). And the asm-x86/desc_64.h file was supposed to be removed by commit c81c6ca4, but instead stayed around containing just a single newline. Get rid of them both properly.

Now that the reference counting on the callback thread is working as expected, it uncovers another problem. Peter Staubach noticed while testing that patch on an older kernel that he would occasionally see this printk in rpc_register fire: "RPC: failed to contact portmap (errno -512). The NFSv4 callback thread is signaled by nfs_callback_down(), but never flushes that signal. All of the shutdown processing is done with that signal pending. This makes it fail the call to unregister the port with the portmapper. In actuality, this rpc_register call isn't necessary at all since the port isn't actually registered with the portmapper anymore. Regardless, there doesn't seem to be any reason to leave the signal pending while the thread is being shut down and flushing it should generally silence that printk.

This is the central patch of a cleanup series. In most cases there is no good reason why someone would want to use a dentry for itself.

Together with the other patches of this series - it enforced the correct order of getting/releasing the reference count on <dentry,vfsmount> pairs - it prepares the VFS for stacking support since it is essential to have a struct path in every place where the stack can be traversed - it reduces the overall code size: without patch series: text data bss dec hex filename 5321639 858418 715768 6895825 6938d1 vmlinux with patch series: text data bss dec hex filename 5320026 858418 715768 6894212 693284 vmlinux This patch: Switch from nd->{dentry,mnt} to nd->path.{dentry,mnt} everywhere.

The compat_sys_mount() system call throws EINVAL for text-based NFSv4 mounts. The text-based mount interface assumes that any mount option blob that doesn't set the version field to "1" is a C string (ie not a legacy mount request). The compat_sys_mount() call treats blobs that don't set the version field to "1" as an error. We just relax the check in compat_sys_mount() a bit to allow C strings to be passed down to the NFSv4 client.

The reference counting for the NFSv4 callback thread stays artificially high. When this thread comes down, it doesn't properly tear down the svc_serv, causing a memory leak. In my testing on an older kernel on x86_64, memory would leak out of the 8k kmalloc slab. So, we're leaking at least a page of memory every time the thread comes down. svc_create() creates the svc_serv with a sv_nrthreads count of 1, and then svc_create_thread() increments that count. Whenever the callback thread is started it has a sv_nrthreads count of 2. When coming down, it calls svc_exit_thread() which decrements that count and if it hits 0, it tears everything down. That never happens here since the count is always at 2 when the thread exits. The problem is that nfs_callback_up() should be calling svc_destroy() on the svc_serv on both success and failure. This is how lockd_up_proto() handles the reference counting, and doing that here fixes the leak.
