A big win, we now save an allocation/free on each request! With the previous rb/hash abstractions, we can just reuse queuelist/donelist for the FIFO data and be done with it. Signed-off-by:Jens Axboe <axboe@suse.de>

Jens Axboe authored
The rbtree sort/lookup/reposition logic is mostly duplicated in cfq/deadline/as, so move it to the elevator core. The io schedulers still provide the actual rb root, as we don't want to impose any sort of specific handling on the schedulers. Introduce the helpers and rb_node in struct request to help migrate the IO schedulers. Signed-off-by: -

The conditions got reserved. Also make rb_next() and rb_prev() check for the empty condition. Signed-off-by: -

Right now, every IO scheduler implements its own backmerging (except for noop, which does no merging). That results in duplicated code for essentially the same operation, which is never a good thing. This patch moves the backmerging out of the io schedulers and into the elevator core. We save 1.6kb of text and as a bonus get backmerging for noop as well. Win-win! Signed-off-by: -

Right now ->flags is a bit of a mess: some are request types, and others are just modifiers. Clean this up by splitting it into ->cmd_type and ->cmd_flags. This allows introduction of generic Linux block message types, useful for sending generic Linux commands to block devices. Signed-off-by: -

Delay the call to adapter->client_register() until after we are certain that the client registration is a success. At this point the client is fully initialized and we no longer hold the adapter->clist mutex, so this should prevent the deadlocks if the client_register() callback needs to take that mutex too, as is the case for the bttv driver. This fixes bug #7234. Signed-off-by:

We only need the timestamp on COOKIE-ECHO chunks, so instead of always timestamping every SCTP packet, let common code timestamp if the socket option is set. For COOKIE-ECHO, simply get the time of day if we don't have a timestamp. This introduces a small possibility that the cookie may be considered expired, but it will be renegotiated. Signed-off-by:

Currently if the sender is sending small messages, it can cause a receiver to run out of receive buffer space even when the advertised receive window is still open and results in packet drops and retransmissions. Including a overhead while updating the sender's view of peer receive window will reduce the chances of receive buffer space overshooting the receive window. Signed-off-by:

MSI is defined to be 32-bit write. The 5706 does 64-bit MSI writes with byte enables disabled on the unused 32-bit word. This is legal but causes problems on the AMD 8132 which will eventually stop responding after a while. Without this patch, the MSI test done by the driver during open will pass, but MSI will eventually stop working after a few MSIs are written by the device. AMD believes this incompatibility is unique to the 5706, and prefers to locally disable MSI rather than globally disabling it using pci_msi_quirk. Update version to 1.4.45. Signed-off-by:

[AK: This apparently broke some systems, but we need it to fix a compile problem with old binutils and in theory the patch is correct. So let's trying reenabling it again.] o Currently bss segment is being placed somewhere in the middle (after .data) section and after bss lots of init section and data sections are coming. Is it intentional? o One side affect of placing bss in the middle is that objcopy keeps the bss in raw binary image (vmlinux.bin) hence unnecessarily increasing the size of raw binary image. (In my case ~600K). It also increases the size of generated bzImage, though the increase is very small (896 bytes), probably a very high compression ratio for stream of zeros. o This patch moves the bss at the end hence reducing the size of bzImage by 896 bytes and size of vmlinux.bin by 600K. o This change benefits in the context of relocatable kernel patches. If kernel bss is not part of compressed data (vmlinux.bin) then it does not have to be decompressed and this area can be used by the decompressor for its execution hence keeping the memory requirements bounded and decompressor code does not stomp over any other data loaded beyond kernel image (As might be the case with bootloaders like kexec).
