The lockdep_assert_irqs_disabled() was a BUG_ON() statement in the

This is no longer the case: the siglock is acquired via

When computing the bitrate using values read from an SFP module EEPROM,
we use the nominal BR plus BR,min and BR,max to determine the
boundaries. But in some cases BR,min and BR,max aren't provided, which

and maximum bitrate v

In an SFP EEPROM values can be read to get information about a given SFP
module. One of those is the bitrate, which can be determined using a
nominal bitrate in addition with min and max values (in %). The SFP code
currently compute both BR,min and BR,max values thanks to this nominal

Make sure to implement the new socketpair callback so the SO_PEERSEC
call on socketpair(2)s will return correct information.

Right now the LSM labels for socketpairs are always uninitialized,
since there is no security hook for the socketpair() syscall. This
patch adds the required hooks so LSMs can properly label socketpairs.
This allows SO_PEERSEC to return useful information on those sockets.
Note that the behavior o
Use the newly created LSM-hook for socketpair(). The default hook
return-value is 0, so behavior stays the same unless LSMs start using
this hook.

When I run "cat /proc/stat" in a container, container will access
host's file directly which is a security risk. LXCFS is a good way
to strengthen the isolation among containers. However, I can not
get a container's correct status because LXCFS just transfer host's
status to container. So I track s

If the system runs with force-threaded interrupts then there is no need

This series avoids/limits disabling of interrupts in drivers/ide.
This is from the -RT queue where it was reported initially (ata was not
widespread back then) and it hurts -RT.
While looking at alim15x3, there are some drivers which exist in both
worlds (alim15x3 included was far as I can tell).
This fixes the parent clock names of the SYSCLKn clocks for the DM355
SoC in the TI DaVinici PLL clock driver.
It appears that this name just didn't get updated to the correct name
like the other SoCs during the driver's development.
