[PATCH v3 0/2] loop: fix two issues introduced by prior commit

[Dongli Zhang <dongli.zhang@xxxxxxxxxx>]

This patch set fix two issues introduced by prior commit.


[PATCH v3 1/2] loop: do not print warn message if partition scan is successful
[PATCH v3 1/2] fixes d57f3374ba48 ("loop: Move special partition reread
handling in loop_clr_fd()") to not always print warn message even when
partition scan is successful.


[PATCH v3 2/2] loop: set GENHD_FL_NO_PART_SCAN after blkdev_reread_part()
[PATCH v3 2/2] fixes 0da03cab87e6 ("loop: Fix deadlock when calling
blkdev_reread_part()") to not set GENHD_FL_NO_PART_SCAN before partition
scan when detaching loop device from the file.

Changed since v1:
  * move the setting of lo->lo_state to Lo_unbound after partscan has finished as well
    (suggested by Jan Kara)

Changed since v2:
  * Put the code inline in __loop_clr_fd() but not introduce new function
    (suggested by Jan Kara)
