Subject: [PATCH tip v6 0/5] Simple wait queue support
Date: Thu, 28 Jan 2016 15:44:25 +0100 [thread overview]
Message-ID: <1453992270-4688-1-git-send-email-daniel.wagner@bmw-carit.de> (raw)
Hi,
The -Werror=incompatible-pointer-types compiler flag is now
unconditionally added. The compile test with various configurations
and architectures didn't show up any show problem. *fingers crossed*
Obviously, the series is rebased and I rerun the KVM tests
to gather more up to date values. That's all for this version.
These patches are against
tip/sched/core 0905f04eb21fc1c2e690bed5d0418a061d56c225
also available as git tree:
git://git.kernel.org/pub/scm/linux/kernel/git/wagi/linux.git tip-swait
cheers,
daniel
changes since v5:
- unconditionally add -Werror=incompatible-pointer-types
- updated KVM statistics in commit message
- rebased on tip/sched/core
- added ack-by PeterZ
changes since v4:
- replaced patch #2 which tried to force to compiler to
exit with an error by using compile time assertion type
check macros. Instead use -Werror=incompatible-pointer-types
to tell the compiler to barf loudly.
- fixed wrong API usage in patch 4 as reported by Boqun.
changes since v3
- rebased it on tip/sched/core (KVM bits have changed slightly)
- added compile time type check assertion
- added non lazy version of swake_up_locked()
changes since v2
- rebased again on tip/master. The patches apply
cleanly on v4.3-rc6 too.
- fixed up mips
- reordered patches to avoid lockdep warning when doing bissect.
- remove unnecessary initialization of rsp->rda in rcu_init_one().
changes since v1 (PATCH v0)
- rebased and fixed some typos found by cross building
for S390, ARM and powerpc. For some unknown reason didn't catch
them last time.
- dropped completion patches because it is not clear yet
how to handle complete_all() calls hard-irq/atomic contexts
and swake_up_all.
changes since v0 (RFC v0)
- promoted the series to PATCH state instead of RFC
- fixed a few fallouts with build all and some cross compilers
such ARM, PowerPC, S390.
- Added the simple waitqueue transformation for KVM from -rt
including some numbers requested by Paolo.
- Added a commit message to PeterZ's patch. Hope he likes it.
[I got the numbering wrong in v1, so instead 'PATCH v1' you find it
as 'PATCH v0' series]
