while not doing free_irq() from irq handler is commendable, kfree() on the
data passed to said handler before free_irq() is Not Good(tm). Freeing
the stack it's being run on is also not nice... Solution: delay actually
freeing stuff.Signed-off-by: Al Viro

tty->count is decremented only after ->close() had been called and
several tasks can hit it in parallel. As the result, using tty->count
to check if you are the last one is broken. We end up leaving line->tty
not reset to NULL and the next IRQ on that sucker will blow up trying to
dereference pointers from kfree'd struct tty.Fix is obvious: we need to use a counter of our own.

Three uml device drivers still use the big kernel lock,
but all of them can be safely converted to using
a per-driver mutex instead. Most likely this is not
even necessary, so after further review these can
and should be removed as well.The exec system call no longer requires the BKL either,
so remove it from there, too.Signed-off-by: Arnd Bergmann

All file_operations should get a .llseek operation so we can make
nonseekable_open the default for future file operations without a
.llseek pointer.The three cases that we can automatically detect are no_llseek, seq_lseek
and default_llseek. For cases where we can we can automatically prove that
the file offset is always ignored, we use noop_llseek, which maintains
the current behavior of not returning an error from a seek.New drivers should normally not use noop_llseek but instead use no_llseek
and call nonseekable_open at open time. Existing drivers can be converted
to do the same when the maintainer knows for certain that no user code
relies on calling seek on the device file.The generated code is often incorrectly indented and right now contains
comments that clarify for each added line why a specific variant was
chosen. In the version that gets submitted upstream, the comments will
be gone and I will manually fix the indentation, because there does not
seem to be a way to do that using coccinelle.Some amount of new code is currently sitting in linux-next that should get
the same modifications, which I will do at the end of the merge window.Many thanks to Julia Lawall for helping me learn to write a semantic
patch that does all this.===== begin semantic patch =====
// This adds an llseek= method to all file operations,
// as a preparation for making no_llseek the default.
//
// The rules are
// - use no_llseek explicitly if we do nonseekable_open
// - use seq_lseek for sequential files
// - use default_llseek if we know we access f_pos
// - use noop_llseek if we know we don't access f_pos,
// but we still want to allow users to call lseek

Commit f81f2f7c (ubd: drop unnecessary rq->sector manipulation)
dropped request->sector manipulation in preparation for global request
handling cleanup; unfortunately, it incorrectly assumed that the
updated sector wasn't being used.ubd tries to issue as many requests as possible to io_thread. When
issuing fails due to memory pressure or other reasons, the device is
put on the restart list and issuing stops. On IO completion, devices
on the restart list are scanned and IO issuing is restarted.ubd issues IOs sg-by-sg and issuing can be stopped in the middle of a
request, so each device on the restart queue needs to remember where
to restart in its current request. ubd needs to keep track of the
issue position itself because,* blk_rq_pos(req) is now updated by the block layer to keep track of
_completion_ position.* Multiple io_req's for the current request may be in flight, so it's
difficult to tell where blk_rq_pos(req) currently is.Add ubd->rq_pos to keep track of the issue position and use it to
correctly restart io_req issue.Signed-off-by: Tejun Heo

uml_net_set_mac() was broken and luckily it was never used, before.
What it was trying to do is spin_lock before memcopy the mac address.
Linus attempted to fix it in assumption that someone decided the
lock was needed. But since it was never ever used at all, and was
just dead code, I think we can assume that it is not needed, after
all.On the other hand patch [f25c80a4] was trying to use eth_mac_addr()
in eth_configure(), *which was the real fallout*. Because of state
checks done inside eth_mac_addr() the address was never set. I have
not reintroduced the memcpy wrapper, but I've put a comment for future
cats.The code now is back to exactly as it was before [f25c80a4]. With
the cleanup applied. If the spin_lock is indeed needed then a contender
should supply a test case that fails, then fix it with the proper
locking, as a separate unrelated patch.CC: Julia Lawall

The open and release block_device_operations are currently
called with the BKL held. In order to change that, we must
first make sure that all drivers that currently rely
on this have no regressions.This blindly pushes the BKL into all .open and .release
operations for all block drivers to prepare for the
next step. The drivers can subsequently replace the BKL
with their own locks or remove it completely when it can
be shown that it is not needed.The functions blkdev_get and blkdev_put are the only
remaining users of the big kernel lock in the block
layer, besides a few uses in the ioctl code, none
of which need to serialize with blkdev_{get,put}.Most of these two functions is also under the protection
of bdev->bd_mutex, including the actual calls to
->open and ->release, and the common code does not
access any global data structures that need the BKL.Signed-off-by: Arnd Bergmann

There are two initializations of ndo_set_mac_address, one to a local
function that is not used otherwise and one to a function that is defined
elsewhere.The semantic match that finds this problem is as follows:

@r@
identifier I, s, fld;
position p0,p;
expression E;
@@struct I s =@p0 { ... .fld@p = E, ...};

position r.p0,p;
expression E;
@@struct I s =@p0 { ... .fld@p = E, ...};
@script:python@

This moves the lock_kernel() call from soundcore_open
to the individual OSS device drivers, where we can deal
with it one driver at a time if needed, or just kill
off the drivers.All core components in ALSA already provide
adequate locking in their open()-functions
and do not require the big kernel lock, so
there is no need to add the BKL there.Signed-off-by: Arnd Bergmann
