commit a647a524a46736786c95cdb553a070322ca096e3 upstream.

rq_qos framework is only applied on request based driver, so:

1) rq_qos_done_bio() needn't to be called for bio based driver

2) rq_qos_done_bio() needn't to be called for bio which isn't tracked,
such as bios ended from error handling code.

Especially in bio_endio():

1) request queue is referred via bio->bi_bdev->bd_disk->queue, which
may be gone since request queue refcount may not be held in above two
cases

2) q->rq_qos may be freed in blk_cleanup_queue() when calling into
__rq_qos_done_bio()

Fix the potential kernel panic by not calling rq_qos_ops->done_bio if
the bio isn't tracked. This way is safe because both ioc_rqos_done_bio()
and blkcg_iolatency_done_bio() are nop if the bio isn't tracked.

commit e06472bab2a5393430cc2fbc3211cd3602422c1e upstream.

The utf16_le_to_7bit function claims to, naively, convert a UTF-16
string to a 7-bit ASCII string. By naively, we mean that it:
 * drops the first byte of every character in the original UTF-16 string
 * checks if all characters are printable, and otherwise replaces them
   by exclamation mark "!".

This means that theoretically, all characters outside the 7-bit ASCII

 * ligature OE (œ) 0x0153 becomes 0x53 (S)
 * hangul letter pieup (ㅂ) 0x3142 becomes 0x42 (B)
 * upper-case gamma (Ɣ) 0x0194 becomes 0x94 (not printable) so gets
   replaced by "!"

The result of this conversion for the GPT partition name is passed to
user-space as PARTNAME via udev, which is confusing and feels questionable.

However, there is a flaw in the conversion function itself. By dropping
one byte of each character and using isprint() to check if the remaining

This happens because we pass 8-bit characters to isprint(), which
