[PATCH] KEYS: fix in-kernel documentation for keyctl_read()

2017-10-26 Thread Eric Biggers
From: Eric Biggers When keyctl_read() is passed a buffer that is too small, the behavior is inconsistent. Some key types will fill as much of the buffer as possible, while others won't copy anything. Moreover, the in-kernel documentation contradicted the man page on this point. Update the in-k

[PATCH] pci: Add a acs_disable option for pci kernel parameter

2017-10-26 Thread sbates
From: Stephen Bates On some servers the BIOS sets up ACS on any valid pci_dev in the system. The kernel has no way of backing this out since the kernel only turns ACS capabilities on. This patch adds a new boot option to the pci kernel parameter called "acs_disable" that will disable ACS. This i
