* [PATCH] prepare vfs_readdir() callers to returning filldir resultAl Viro2008-10-23
| | | | | | | It's not the final state, but it allows moving ->readdir() instances to passing filldir return value to caller of vfs_readdir(). Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

* [PATCH] get rid of on-stack fake dentry in ext3_get_parent()Al Viro2008-10-23
| | | | | | | | Better pass parent and qstr to ext3_find_entry() explicitly than use such kludges, especially since the stack footprint is nasty enough and we have every chance to be deep in call chain. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
* [JFFS2] Reinstate NFS exportabilityDavid Woodhouse2008-10-23
| | | | | | | | | | | Now that the readdir/lookup deadlock issues have been dealt with, we can export JFFS2 file systems again. (For now, you have to specify fsid manually; we should add a method to the export_ops to handle that too.)

* [PATCH] Remove XFS buffered readdir hackDavid Woodhouse2008-10-23
| | | | | | | | Now that we've moved the readdir hack to the nfsd code, we can remove the local version from the XFS code. Signed-off-by: David Woodhouse <David.Woodhouse@intel.com> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
* [PATCH] Copy XFS readdir hack into nfsd code.David Woodhouse2008-10-23
| | | | | | | | | | | | | | | | | | | | | Some file systems with their own internal locking have problems with the way that nfsd calls the ->lookup() method from within a filldir function called from their ->readdir() method. The recursion back into the file system code can cause deadlock. XFS has a fairly hackish solution to this which involves doing the readdir() into a locally-allocated buffer, then going back through it calling the filldir function afterwards. It's not ideal, but it works. It's particularly suboptimal because XFS does this for local file systems too, where it's completely unnecessary. Copy this hack into the NFS code where it can be used only for NFS export. In response to feedback, use it unconditionally rather than only for the affected file systems.

* [PATCH] new helper: d_obtain_aliasChristoph Hellwig2008-10-23
| | | | | | | | | | | | | | | | The calling conventions of d_alloc_anon are rather unfortunate for all users, and it's name is not very descriptive either. Add d_obtain_alias as a new exported helper that drops the inode reference in the failure case, too and allows to pass-through NULL pointers and inodes to allow for tail-calls in the export operations. Incidentally this helper already existed as a private function in libfs.c as exportfs_d_alloc so kill that one and switch the callers to d_obtain_alias.

* binfmt_elf_fdpic: Update for cputime changes.Paul Mundt2008-10-20
| | | | | | | | | | | | | Commit f06febc96ba8e0af80bcc3eaec0a109e88275fac ("timers: fix itimer/ many thread hang") introduced a new task_cputime interface and subsequently only converted binfmt_elf over to it. This results in the build for binfmt_elf_fdpic blowing up given that p->signal->{u,s}time have disappeared from underneath us. Apply the same trivial fix from binfmt_elf to binfmt_elf_fdpic.

* Export tiny shmem_file_setup for DRM-GEMHugh Dickins2008-10-20
| | | | | | | | | | | | | We're trying to keep the !CONFIG_SHMEM tiny-shmem.c (using ramfs without swap) in synch with CONFIG_SHMEM shmem.c (and mpm is preparing patches to combine them). I was glad to see EXPORT_SYMBOL_GPL(shmem_file_setup) go into shmem.c, but why not support DRM-GEM when !CONFIG_SHMEM too? But caution says still depend on MMU, since !CONFIG_MMU is.. different.

| * parisc: hijack jump to start_kernelKyle McMartin2008-10-10
| | | | | | | | | | | | | | | | | | | | | | | | Bang in our own start_parisc call, which initializes the PDC width, and turns on the FPU. Previously, if CONFIG_PRINTK_TIME was on, we'd attempt to use the FPU before we had enabled it, resulting in a difficult to diagnose panic. This patch causes init_per_cpu to redundantly set these for cpu0, but this is harmless.
| * parisc: add pdc_coproc_cfg_unlocked and set_firmware_width_unlockedKyle McMartin2008-10-10
| | | | | | | | | | | | | | These functions are called only when bringing up the monarch cpu, so it is safe to call them without taking the pdc spinlock. In the future, this may become relevant for lockdep, since these functions were taking spinlocks before start_kernel called the lockdep initializers.

Make the special case be a nice inlien function of its own, clean up the code, and make the warning go away. I wish people didn't write code that gets (valid) warnings from the compiler, but I'll limit my fixes to code that I actually care about (in this case just because I see the warning and it annoys me).
