This patch drops the log spinlock when an I/O error occurs to avoid any possible problems in case of blocking or recursion in the I/O error routine. It also has a few cosmetic changes to tidy up various other files. Signed-off-by: NSteven Whitehouse <swhiteho@redhat.com>

The original code ordered the blocks allocated in the build_height routine backwards causing excessive disk seeks during a read of the metadata. This patch reverses the order to try and reduce disk seeks. Example: A five level metadata tree, I = Inode, P = Pointers, D = Data You need to read the blocks in the order: I P5 P4 P3 P2 P1 D in order to read a single data block. The new code now orders the blocks in this way. The old code used to order them as: I P1 P2 P3 P4 P5 D requiring two extra seeks on average. Note that for files which are grown by gradual extension rather than by truncate or by llseek/write at a large offset, this doesn't apply. In the case of writing to a file linearly, this routine will only be called upon to extend the height of the tree by one block at a time, so the ordering is determined by when its called rather than by the internals of the routine itself. Optimising that part of the ordering is a much harder problem. Signed-off-by: NSteven Whitehouse <swhiteho@redhat.com>

Don't recurse back into the driver even if the unplug threshold is met, when the driver asks for a requeue. This is both silly from a logical point of view (requeues typically happen due to driver/hardware shortage), and also dangerous since we could hit an endless request_fn -> requeue -> unplug -> request_fn loop and crash on stack overrun. Also limit blk_run_queue() to one level of recursion, similar to how blk_start_queue() works. This patch fixed a real problem with SLES10 and lpfc, and it could hit any SCSI lld that returns non-zero from it's ->queuecommand() handler.

Eric Biederman points out that we can't take the task_lock while holding tasklist_lock for writing, because another CPU that holds the task lock might take an interrupt that then tries to take tasklist_lock for writing. Which would be a nasty deadlock, with one CPU spinning forever in an interrupt handler (although admittedly you need to really work at triggering it ;) Since the ptrace_attach() code is special and very unusual, just make it be extra careful, and use trylock+repeat to avoid the possible deadlock.

-
由 James Cameron 提交于
661FX7MI-S motherboard which uses the SiS 661FX chipset. The patch adds an entry to mii_chip_info for the transceiver. The PHY ids were found using the sis900_c_122.diff patch from http://brownhat.org/sis900.html but that patch didn't solve the problem, because the PHY at address 1 was already being chosen. Without my patch, when bursts of packets arrive from other hosts on a LAN, the interface dropped one roughly 10% of the time, causing retransmits. There were fifth second pauses in refresh of large xterms, and it made Netrek suck. I can provide further test data. Workaround in lieu of patch is to use mii-tool to advertise 100baseTx-HD, then force renegotiation. I wasn't able to identify the actual transceiver, so the description field is a guess. This patch is similar to Artur Skawina's patch: http://marc.theaimsgroup.com/?l=linux-netdev&m=114297516729079&w=2 I'm not sure, but I wonder if it means the default behaviour should be changed, so as to better handle future transceivers.

The last step of netdevice registration was being done by a delayed call, but because it was delayed, it was impossible to return any error code if the class_device registration failed. Side effects: * one state in registration process is unnecessary. * register_netdevice can sleep inside class_device registration/hotplug * code in netdev_run_todo only does unregistration so it is simpler.

A race condition exists in mptfc between the thread registering a device with the fc transport and the scan work generated by the transport. This race existed prior to the application of the mptfc bug fix patch. mptfc_register_dev() calls fc_remote_port_add() with the FC_RPORT_ROLE_TARGET bit set in the rport ids passed to the function. Having this bit set causes fc_remote_port_add() to schedule a scan of the device. This scan can execute before mptfc_register_dev() can fill in the dd_data in the rport structure. When this happens, mptfc_target_alloc() will fail because dd_data is null. Attached is a patch which fixes the problem. The patch changes the rport ids passed to fc_remote_port_add() to not have the TARGET bit set. This prevents the scan from being scheduled. After mptfc_register_dev() fills in the rport dd_data field, fc_remote_port_rolechg() is called, changing the role of the rport to TARGET. Thus, the scan is scheduled after dd_data is filled in which prevents the failure in mptfc_target_alloc().

tg3_run_loopback doesn't check that dev_alloc_skb() returns anything useful. Even if dev_alloc_skb() fails to return an skb to us we'll happily go on and assume it did, so we risk dereferencing a NULL pointer.

The test used in the linkwatch does not handle wrap-arounds correctly. Since the intention of the code is to eliminate bursts of messages we can afford to delay things up to a second. Using that fact we can easily handle wrap-arounds by making sure that we don't delay things by more than one second. This is based on diagnosis and a patch by Stefan Rompf.
