CONFIG_EXT3_INDEX is not an exposed config option in the kernel, and it is unconditionally defined in ext3_fs.h. tune2fs is already able to turn off dir indexing, so at this point it's just cluttering up the code. Remove it. Signed-off-by:

The early LFS work that Linux uses favours EFBIG in various places. SuSv3 specifically uses EOVERFLOW for this as noted by Michael (Bug 7253) [EOVERFLOW] The named file is a regular file and the size of the file cannot be represented correctly in an object of type off_t. We should therefore transition to the proper error return code Signed-off-by:Alan Cox <alan@redhat.com> Cc: Theodore Tso <tytso@mit.edu> Cc: Jens Axboe <jens.axboe@oracle.com> Cc: Arjan van de Ven <arjan@infradead.org> Signed-off-by:

Compiling handle_percpu_irq only on uniprocessor generates an artificial special case so a typical use like: set_irq_chip_and_handler(irq, &some_irq_type, handle_percpu_irq); needs to be conditionally compiled only on SMP systems as well and an alternative UP construct is usually needed - for no good reason. This fixes uniprocessor configurations for some MIPS SMP systems. Signed-off-by:

Only very little files use the deprecated SA_* IRQ flags in latest pull. This patch series removes such macros from the tree and transfrom old code to the new IRQF_* flags. I've grepped the whole tree to make sure that no more files than the patched ones use such deprecated macros. I hope this series won't introduce build errors. Signed-off-by:

Since we know the shared inode count is always >0, we can avoid igrab() and use an open coded atomic_inc(). This also fixes a bug noticed by Yan Zheng <yanzheng@21cn.com>: were checking for an IS_ERR() return from igrab(), but it actually returns NULL on error. Signed-off-by:

This changes hvc_init() to be called only when someone actually uses the hvc_console driver. Dave Jones complained when profiling bootup. hvc_console used to only be for Power aka pSeries: now lguest and Xen both want it built-in in case the kernel is a guest under one of those, even though usually it will be a native boot.

include/asm-powerpc/elf.h has 6 entries in ARCH_DLINFO. fs/binfmt_elf.c has 14 unconditional NEW_AUX_ENT entries and 2 conditional NEW_AUX_ENT entries. So in the worst case, saved_auxv does not get an AT_NULL entry at the end. The saved_auxv array must be terminated with an AT_NULL entry. Make the size of mm_struct->saved_auxv arch dependend, based on the number of ARCH_DLINFO entries. Signed-off-by:

This patch does additional coding style fixup. Initially the code is being distorted by Lindent (in my patches sent not very long ago) and fixed in the followup patches but this stuff was accidently missed. New and old compiled files were compared with cmp to check for being identically. So the patch will not break the kernel. Signed-off-by:

This adds three new functions (or in one case to be more exact makes it always available) tty_termios_copy_hw Copies all the hardware settings from one termios structure to the other. This is intended for drivers that support little or no hardware setting tty_termios_encode_baud_rate Allows you to set the input and output baud rate in a termios structure. A driver is supposed to set the resulting baud rate from a request so most will want to use this function to set the resulting input and output rates to match the hardware values. Internally it knows about keeping Bxxx encoding when possible to maximise compatibility. tty_encode_baud_rate As above but for the tty's own current termios structure I suspect this will initially need some tweaking as it gets enabled by driver patches over the next few mm cycles so consider this lot -mm only for the moment so it can stabilize and end up neat before it goes to base. I've tried not to break any obscure architectures - if you get a speed you can't represent the code will print warnings on non updated termios systems but not break. Once this is merged and seems sane I've got a growing pile of driver updates to use it - notably for USB serial drivers. [akpm@linux-foundation.org: cleanups] Signed-off-by:

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.

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:
