If skinny metadata is enabled and our first tree search fails to find a
skinny extent item, we may repeat a tree search for a "fat" extent item
(if the previous item in the leaf is not the "fat" extent we're looking
for). However we were not setting the new key's objectid to the right
value, as we previously used the same key variable to peek at the previous
item in the leaf, which has a different objectid. So just set the right
objectid to avoid modifying/deleting a wrong item if we repeat the tree
search.

Currently, with inode cache enabled, we will reuse its inode id immediately
after unlinking file, we may hit something like following:
|->iput inode
|->return inode id into inode cache
|->create dir,fsync
|->power off
An easy way to reproduce this problem is:
mkfs.btrfs -f /dev/sdb
mount /dev/sdb /mnt -o inode_cache,commit=100
dd if=/dev/zero of=/mnt/data bs=1M count=10 oflag=sync
inode_id=`ls -i /mnt/data | awk '{print $1}'`
rm -f /mnt/data
i=1
while [ 1 ]
do
mkdir /mnt/dir_$i
test1=`stat /mnt/dir_$i | grep Inode: | awk '{print $4}'`
if [ $test1 -eq $inode_id ]
then
dd if=/dev/zero of=/mnt/dir_$i/data bs=1M count=1 oflag=sync
echo b > /proc/sysrq-trigger
fi
sleep 1
i=$(($i+1))
done
mount /dev/sdb /mnt
umount /dev/sdb
btrfs check /dev/sdb
We fix this problem by adding unlinked inode's id into pinned tree,
and we can not reuse them until committing transaction.

breaking user space API, to reflect the Cadence origin. This is achieved
through simple search and replace:

The only exceptions are PORT_XUARTPS and the driver name, which stay as is,

In the uart_handle_cts_change(), uart_write_wakeup() is called after
we call @uart_port->ops->start_tx().
The Documentation/serial/driver tells us:
-----------------------------------------------
start_tx(port)
Start transmitting characters.
Locking: port->lock taken.
Interrupts: locally disabled.
-----------------------------------------------
So when the uart_write_wakeup() is called, the port->lock is taken by
the upper. See the following callstack:
|_ uart_write_wakeup
|_ tty_wakeup
|_ ld->ops->write_wakeup
With the port->lock held, we call the @write_wakeup. Some implemetation of
the @write_wakeup does not notice that the port->lock is held, and it still
tries to send data with uart_write() which will try to grab the prot->lock.
A dead lock occurs, see the following log caught in the Bluetooth by uart:

In (efe2f29 kgdboc,kdb: Allow kdb to work on a non open console port)
support was added to directly use the "write_char" functions when
doing kdb over a non-open console port. This is great, but it ends up
bypassing the normal code in uart_console_write() that adds a carriage
return before any newlines.
There appears to have been a trend to add this support directly in
some console driver's poll_put_char() functions. This had a few side
effects, including:
- In this case we were doing LFCR, not CRLF. This was fixed in
uart_console_write() back in (d358788 [SERIAL] kernel console should
send CRLF not LFCR)
- Not all serial drivers had the LFCR code in their poll_put_char()
functions. In my case I was running serial/samsung.c which lacked
it.
I've moved the handling to uart_poll_put_char() to fix the above
problems. Now when I use kdb (and don't point console= to the same
UART) I no longer get:

Not only does this impose a pointless (but tiny) runtime overhead for

While porting a RS485 driver from 2.6.29 to 3.14, i noticed that the serial tty
driver could break it by using uart ports that it does not own :
1. uart_change_pm ist called during uart_open and calls the uart pm function
without checking for PORT_UNKNOWN.
The fix is to move uart_change_pm from uart_open to uart_port_startup.
2. The return code from the uart request_port call in uart_set_info is not
handled properly, leading to the situation that the serial driver also
thinks it owns the uart ports.
This can triggered by doing following actions :
setserial /dev/ttyS0 uart none # release the uart ports
modprobe lirc-serial # or any other device that uses the uart
setserial /dev/ttyS0 uart 16550 # gives no error and the uart tty driver
# can use the ports as well

One used a barrier() in its loop and the other a cpu_relax(). The

The two functions in the samsung serial driver used for writing
characters out to the port were inconsistent about whether they used
the passed in "port" or the global "cons_uart". There was no reason
to use the global and the use of the global in
s3c24xx_serial_put_poll_char() caused a crash in the case where you
used the serial port for kgdboc but not for console.
Fix it so we used the passed in variable.
Note that this doesn't fix all problems with the samsung serial
driver. Specifically:
* s3c24xx_serial_console_putchar() is still 99% identical to
s3c24xx_serial_put_poll_char() (the function signature is different,
but that's about it). A future patch will make them slightly less
identical and judging by other serial drivers we may need yet more
differences eventually.
* The samsung serial driver still doesn't allow you to have more than
one console port since it still uses the global cons_uart in
s3c24xx_serial_console_write().

The race was introduced while development of linux-3.11 by
e8437d7ecb and
e9975fdec0.
Originally it was found and reproduced on linux-3.12.15 and
linux-3.12.15-rt25, by sending 500 byte blocks with 115kbaud to the
target uart in a loop with 100 milliseconds delay.
In short:
1. The consumer flush_to_ldisc is on to remove the head tty_buffer.
2. The producer adds a number of bytes, so that a new tty_buffer must
be allocated and added by __tty_buffer_request_room.
3. The consumer removes the head tty_buffer element, without handling
newly committed data.
Detailed example:
* Initial buffer:
* Head, Tail -> 0: used=250; commit=250; read=240; next=NULL
* Consumer: ''flush_to_ldisc''
* consumed 10 Byte
* buffer:
* Head, Tail -> 0: used=250; commit=250; read=250; next=NULL
{{{
count = head->commit - head->read; // count = 0
if (!count) { // enter
// INTERRUPTED BY PRODUCER ->
if (head->next == NULL)
break;
buf->head = head->next;
tty_buffer_free(port, head);
continue;
}
}}}
* Producer: tty_insert_flip_... 10 bytes + tty_flip_buffer_push
* buffer:
* Head, Tail -> 0: used=250; commit=250; read=250; next=NULL
* added 6 bytes: head-element filled to maximum.
* buffer:
* Head, Tail -> 0: used=256; commit=250; read=250; next=NULL
* added 4 bytes: __tty_buffer_request_room is called
* buffer:
* Head -> 0: used=256; commit=256; read=250; next=1
* Tail -> 1: used=4; commit=0; read=250 next=NULL
* push (tty_flip_buffer_push)
* buffer:
* Head -> 0: used=256; commit=256; read=250; next=1
* Tail -> 1: used=4; commit=4; read=250 next=NULL
* Consumer
{{{
count = head->commit - head->read;
if (!count) {
// INTERRUPTED BY PRODUCER <-
if (head->next == NULL) // -> no break
break;
buf->head = head->next;
tty_buffer_free(port, head);
