The GD_NEED_PART_SCAN is set by bdev_check_media_change to initiate a partition scan while removing a block device. It should be cleared after blk_drop_paritions because blk_drop_paritions could return -EBUSY and then the consequence __blkdev_get has no chance to do delete_partition if GD_NEED_PART_SCAN already cleared. It causes some problems on some card readers. Ex. Realtek card reader 0bda:0328 and 0bda:0158. The device node of the partition will not disappear after the memory card removed. Thus the user applications can not update the device mapping correctly.

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
