* [PATCH] Slab: Do not fallback to nodes that have not been bootstrapped yetChristoph Lameter2006-10-21
| | | | | | | | | | | | | | | | | | | | | The zonelist may contain zones of nodes that have not been bootstrapped and we will oops if we try to allocate from those zones. So check if the node information for the slab and the node have been setup before attempting an allocation. If it has not been setup then skip that zone. Usually we will not encounter this situation since the slab bootstrap code avoids falling back before we have setup the respective nodes but we seem to have a special needs for pppc.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Separate out the concept of "queue congestion" from "backing-dev congestion". Congestion is a backing-dev concept, not a queue concept. The blk_* congestion functions are retained, as wrappers around the core backing-dev congestion functions. This proper layering is needed so that NFS can cleanly use the congestion functions, and so that CONFIG_BLOCK=n actually links.

|/ | | | | | | | | | | | | | | | | | buffered write When direct-io falls back to buffered write, it will just leave the dirty data floating about in pagecache, pending regular writeback. But normal direct-io semantics are that IO is synchronous, and that it leaves no pagecache behind. So change the fallback-to-buffered-write code to sync the file region and to then strip away the pagecache, just as a regular direct-io write would do.

* [PATCH] knfsd: add nfs-export support to tmpfsDavid M. Grimes2006-10-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We need to encode a decode the 'file' part of a handle. We simply use the inode number and generation number to construct the filehandle. The generation number is the time when the file was created. As inode numbers cycle through the full 32 bits before being reused, there is no real chance of the same inum being allocated to different files in the same second so this is suitably unique. Using time-of-day rather than e.g. jiffies makes it less likely that the same filehandle can be created after a reboot. In order to be able to decode a filehandle we need to be able to lookup by inum, which means that the inode needs to be added to the inode hash table (tmpfs doesn't currently hash inodes as there is never a need to lookup by inum). To avoid overhead when not exporting, we only hash an inode when it is first exported. This requires a lock to ensure it isn't hashed twice. This code is separate from the patch posted in June06 from Atal Shargorodsky which provided the same functionality, but does borrow slightly from it. Locking comment: Most filesystems that hash their inodes do so at the point where the 'struct inode' is initialised, and that has suitable locking (I_NEW). Here in shmem, we are hashing the inode later, the first time we need an NFS file handle for it. We no longer have I_NEW to ensure only one thread tries to add it to the hash table.

| | | | | | | | | | | | | | | If try_to_release_page() is called with a zero gfp mask, then the filesystem is effectively denied the possibility of sleeping while attempting to release the page.

For this reason, change the gfp_mask argument of the call to GFP_KERNEL.

* [PATCH] hugetlb: fix linked list corruption in unmap_hugepage_range()Chen, Kenneth W2006-10-11
| | | | | | | | | | | | | | | | commit fe1668ae5bf0145014c71797febd9ad5670d5d05 causes kernel to oops with libhugetlbfs test suite. The problem is that hugetlb pages can be shared by multiple mappings. Multiple threads can fight over page->lru in the unmap path and bad things happen. We now serialize __unmap_hugepage_range to void concurrent linked list manipulation. Such serialization is also needed for shared page table page on hugetlb area. This patch will fixed the bug and also serve as a prepatch for shared page table.

* [PATCH] page fault retry with NOPAGE_REFAULTBenjamin Herrenschmidt2006-10-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a way for a no_page() handler to request a retry of the faulting instruction. It goes back to userland on page faults and just tries again in get_user_pages(). I added a cond_resched() in the loop in that later case. The problem I have with signal and spufs is an actual bug affecting apps and I don't see other ways of fixing it. In addition, we are having issues with infiniband and 64k pages (related to the way the hypervisor deals with some HV cards) that will require us to muck around with the MMU from within the IB driver's no_page() (it's a pSeries specific driver) and return to the caller the same way using NOPAGE_REFAULT. And to add to this, the graphics folks have been following a new approach of memory management that involves transparently swapping objects between video ram and main meory. To do that, they need installing PTEs from a no_page() handler as well and that also requires returning with NOPAGE_REFAULT. (For the later, they are currently using io_remap_pfn_range to install one PTE from no_page() which is a bit racy, we need to add a check for the PTE having already been installed afer taking the lock, but that's ok, they are only at the proof-of-concept stage. I'll send a patch adding a "clean" function to do that, we can use that from spufs too and get rid of the sparsemem hacks we do to create struct page for SPEs. Basically, that provides a generic solution for being able to have no_page() map hardware devices, which is something that I think sound driver folks have been asking for some time too). All of these things depend on having the NOPAGE_REFAULT exit path from no_page() handlers.
