There is possible dead loop in finish_unfinished function. In most situation, the call chain iput -> ... -> reiserfs_delete_inode -> remove_save_link will success. But for some reason such as data corruption, reiserfs_delete_inode fails on reiserfs_do_truncate -> search_for_position_by_key. Then remove_save_link won't be called. We always get the same "save_link_key" in the while loop in finish_unfinished function. The following patch adds a check for the possible dead loop and just remove save link when deap loop.

This patch makes shrink_dcache_sb consistent with dentry pruning policy. On the first pass we iterate over dentry unused list and prepare some dentries for removal. However, since the existing code moves evicted dentries to the beginning of the LRU it can happen that fresh dentries from other superblocks will be inserted *before* our dentries. This can result in significant slowdown of shrink_dcache_sb(). Moreover, for virtual filesystems like unionfs which can call dput() during dentries kill existing code results in O(n^2) complexity. We observed 2 minutes shrink_dcache_sb() with only 35000 dentries. To avoid this effects we propose to isolate sb dentries at the end of LRU list. Signed-off-by:

Remove the old-fashioned lk201 driver under drivers/tc/ that used to be used by the old dz.c and zs.c drivers, which is now orphan code referred to from nowhere and does not build anymore. A modern replacement is available as drivers/input/keyboard/lkkbd.c. There are no plans to do anything about this piece of code and it does not fit anywhere anymore, so it is not just a matter of maintenance or the lack of. There are still some bits that might be added to the new lkkbd.c driver based on the old code, and the embedded hardware documentation which is otherwise quite hard to get hold of might be useful to keep too. Both of these can be done separately though. RIP. Signed-off-by:

Make request_key() and co fundamentally asynchronous to make it easier for NFS to make use of them. There are now accessor functions that do asynchronous constructions, a wait function to wait for construction to complete, and a completion function for the key type to indicate completion of construction. Note that the construction queue is now gone. Instead, keys under construction are linked in to the appropriate keyring in advance, and that anyone encountering one must wait for it to be complete before they can use it. This is done automatically for userspace. The following auxiliary changes are also made: (1) Key type implementation stuff is split from linux/key.h into linux/key-type.h. (2) AF_RXRPC provides a way to allocate null rxrpc-type keys so that AFS does not need to call key_instantiate_and_link() directly. (3) Adjust the debugging macros so that they're -Wformat checked even if they are disabled, and make it so they can be enabled simply by defining __KDEBUG to be consistent with other code of mine. (3) Documentation. [alan@lxorguk.ukuu.org.uk: keys: missing word in documentation] Signed-off-by:David Howells <dhowells@redhat.com> Signed-off-by:

reiserfs_invalidatepage will refuse to free pages if they have been logged in data=journal mode, or were pinned down by a data=ordered operation. For data=journal, this is fairly easy to trigger just with fsx-linux, and it results in a large number of pages hanging around on the LRUs with page->mapping == NULL. Calling try_to_free_buffers when reiserfs decides it is done with the page allows it to be freed earlier, and with much less VM thrashing. Lock ordering rules mean that reiserfs can't call lock_page when it is releasing the buffers, so TestSetPageLocked is used instead. Contention on these pages should be rare, so it should be sufficient most of the time. Signed-off-by:

dma_cache_(wback|inv|wback_inv) were the earliest attempt on a generalized cache managment API for I/O purposes. Originally it was basically the raw MIPS low level cache API exported to the entire world. The API has suffered from a lack of documentation, was not very widely used unlike it's more modern brothers and can easily be replaced by dma_cache_sync. So remove it rsp. turn the surviving bits back into an arch private API, as discussed on linux-arch. Signed-off-by:

As of now, the kernel defaults to non-unicode and XLATE for the keyboard. We've been changing this in Fedora, but that requires patching the defaults in the kernel. The attached introduces CONFIG_VT_UNICODE, which sets the console in unicode mode by default on boot, including both the virtual terminal and the keyboard driver. Signed-off-by:

Negative shifts are not allowed in C (the result is undefined). Same thing with full-width shifts. It works on most platforms but not on the VAX with gcc 4.0.1 (it results in an "operand reserved" fault). Shifting by more than the width of the value on the left is also not allowed. I think the extra '>> 1' tacked on at the end in the original code was an attempt to work around that. Getting rid of that is an extra feature of this patch. Here's the chapter and verse, taken from the final draft of the C99 standard ("6.5.7 Bitwise shift operators", paragraph 3): "The integer promotions are performed on each of the operands. The type of the result is that of the promoted left operand. If the value of the right operand is negative or is greater than or equal to the width of the promoted left operand, the behavior is undefined." Thank you to Jan-Benedict Glaw, Christoph Hellwig, Maciej Rozycki, Pekka Enberg, Andreas Schwab, and Christoph Lameter for review. Special thanks to Andreas for spotting that my fix only removed half the undefined behaviour.

Various architectures may call bust_spinlocks() recursively; the function itself, however, doesn't appear to be meant to be called in this manner. Nevertheless, this doesn't appear to be a problem as long as bust_spinlocks(0) doesn't get called twice in a row (otherwise, unblank_screen() may enter the scheduler). However, at least on i386 die() has been capable of returning (and on other architectures this should really be that way, too) when notify_die() returns NOTIFY_STOP. Short of getting a reply to a respective query, this patch makes bust_spinlocks() increment/decrement oops_in_progress, and wake klogd only when the count drops back to zero. Signed-off-by:

Implement sending of quota messages via netlink interface. The advantage is that in userspace we can better decide what to do with the message - for example display a dialogue in your X session or just write the message to the console. As a bonus, we can get rid of problems with console locking deep inside filesystem code once we remove the old printing mechanism. Signed-off-by:

Grant Grundler was asking for more detail about correct usage of local atomic operations and suggested adding the resulting summary to local_ops.txt. "Please add a bit more detail. If DaveM is correct (he normally is), then there must be limits on how the local_t can be used in the kernel process and interrupt contexts. I'd like those rules spelled out very clearly since it's easy to get wrong and tracking down such a bug is quite painful." Signed-off-by:

Since CONFIG_RAMFS is currently hard-selected to "y", and since Documentation/filesystems/ramfs-rootfs-initramfs.txt reads as follows: "The amount of code required to implement ramfs is tiny, because all the work is done by the existing Linux caching infrastructure. Basically, you're mounting the disk cache as a filesystem. Because of this, ramfs is not an optional component removable via menuconfig, since there would be negligible space savings." It seems pointless to leave this as a Kconfig entry. Signed-off-by:
