I don't think that has the leak fixes in it yet. I'm looking here: http://git.kernel.org/cgit/linux/kernel/git/davem/net-next.git/log/drivers/pci/msi.c which does not contain the fixes from 2014-02-13 that are listed here: http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/log/drivers/pci/msi.c In particular, these two look related: PCI/MSI: Fix leak of msi_attrs PCI/MSI: Check kmalloc() return value, fix leak of name So if you do look into them further, make sure you pick up these fixes first, and let me know if you still see issues.
