About lkp compare ERROR
by xly
Hello,
When I run the command "lkp compare RESULT_ROOT0 RESULT_ROOT1"， I get the following error message, How should I fix it ?
/home/chy/lkp-tests/lib/stats.rb:177:in `matrix_cols': undefined method `size' for 277651.44:Float (NoMethodError)

Re: [LKP] [PATCH 2/3] rhashtable-test: retry insert operations in threads

Absolutely not. The only reason for an insertion to fail is if we
can't allocate enough memory. Unless the user is also looping its
kmalloc calls it definitely shouldn't be retrying the insert.
If an expansion fails it means either that the system is suffering
a catastrophic memory shortage, or the user of rhashtable is doing
something wrong.

[PCI, x86] 991de2e590: EIP is at _raw_spin_unlock_irqrestore
by kernel test robot
Greetings,
0day kernel testing robot got the below dmesg and the first bad commit is
git://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git master
commit 991de2e59090e55c65a7f59a049142e3c480f7bd
Author: Jiang Liu <jiang.liu(a)linux.intel.com>
AuthorDate: Wed Jun 10 16:54:59 2015 +0800
Commit: Bjorn Helgaas <bhelgaas(a)google.com>
CommitDate: Thu Jul 30 14:05:57 2015 -0500
PCI, x86: Implement pcibios_alloc_irq() and pcibios_free_irq()
To support IOAPIC hotplug, we need to allocate PCI IRQ resources on demand
and free them when not used anymore.
Implement pcibios_alloc_irq() and pcibios_free_irq() to dynamically
allocate and free PCI IRQs.
Remove mp_should_keep_irq(), which is no longer used.
