This patch serie introduce, step by step the kernel module parameter
max_beb_per1024, then the ioctl and finally drop the kernel config option
CONFIG_MTD_UBI_BEB_LIMIT.
It's based on top of linux-ubi/master (4ebb4b5)
Changelog:
V2..V3:
* Suppress the possibility to have an empty string for vid_hdr_offs and
max_beb_per1024 and change the module info accordingly.
* add the Reviewed-by of Shmulik on the 1st patch.
V1..V2:
* The upper bound of max_beb_per1024 is checked and set to 768
* The vid_hdr_offs parameter can now be an empty string in order to have a
kernel parameter like that: mtd.ubi=2,,25
* The max_beb_per1024 parameter can also be empty (just for consistency with
vid_hdr_offs)
* The comment in ubi-user.h has been adjusted with the new range 0-768 and
the term "default kernel value" is used in place of MTD_UBI_DEFAULT_BEB_LIMIT
or CONFIG_MTD_UBI_BEB_LIMIT
* As max_beb_per1024 can be safely null, the config range of MTD_UBI_BEB_LIMIT
has been updates to 0..768
* For the ioctl, max_beb_per1024 is now an __u16, so that we are not limited
to 255 anymore.
* The comment on the default value of max_beb_per1024 has been adjusted before
and after the ioctl patch.
Best Regards
Richard.
