12 years agoNFS: Avoid a deadlock situation on write
Trond Myklebust [Sun, 20 May 2007 14:18:27 +0000]
NFS: Avoid a deadlock situation on write

When processes are allowed to attempt to lock a non-contiguous range of nfs
write requests, it is possible for generic_writepages to 'wrap round' the
address space, and call writepage() on a request that is already locked by
the same process.

We avoid the deadlock by checking if the page index is contiguous with the
list of nfs write requests that is already held in our
nfs_pageio_descriptor prior to attempting to lock a new request.

ide/pci/serverworks.c: Fix corruption/timeouts with MegaIDE

It turns out from customer reports to Red Hat and some PCI dumps that the
MegaIDE in RAID mode doesn't provide the drive tuning data that the
serverworks driver expects but sometimes does provide something that
fools the code.

For the RAID class case skip the oem setup and don't trust the BIOS data.
We then tune from scratch and this sorts it out. (This has been confirmed
on an afflicted IBM blade)

[libata serverworks.c never trusts the BIOS in the first place so is
accidentally immune]

The Sitecom WL-117 is another "driverless" ZD1211 device where the virtual

Input: ads7846 - SPI_CPHA mode bugfix

In commit [1] the SPI mode is set to 1, but it should be 0.  As stated
in the commit, ads784x samples the data on the rising edge.  SPI mode 1
samples on the falling edge [2] though.

The root cause of this is a bug in the omap_uwire code, which treats
CPHA=1 incorrectly; so these two bugs cancel each other out on one
of the main regression test platforms for this driver.

[POWERPC] Fix typo: MMCR0_PMA0 != MMCR0_PMAO

pmc.c has:

#ifndef MMCR0_PMA0
#define MMCR0_PMA0     0

This one took a while to find.  Unfortunately its the wrong define
(number 0 vs letter O). Its probably worth removing this override, since
if our includes get screwed up we will have the same (hard to debug)
failure.

Fix it simply for now, so that we can backport to stable.

Michael S. Tsirkin [Mon, 21 May 2007 16:06:54 +0000]
IB/cm: Improve local id allocation

The IB CM uses an idr for local id allocations, with a running counter
as start_id.  This fails to generate distinct ids if

1. An id is constantly created and destroyed
2. A chunk of ids just beyond the current next_id value is occupied

This in turn leads to an increased chance of connection request being
mis-detected as a duplicate, sometimes for several retries, until
next_id gets past the block of allocated ids. This has been observed
in practice.

As a fix, remember the last id allocated and start immediately above it.
This also fixes a problem with the old code, where next_id might
overflow and become negative.

SRQ WR leakage has been observed with IPoIB/CM: e.g. flipping ports on

will start getting RNR NAKs.  Fix this in the way suggested by spec:
move the QP being destroyed to the error state, wait for "Last WQE
Reached" event and then post WR on a "drain QP" connected to the same
CQ.  Once we observe a completion on the drain QP, it's safe to call
