ubi: fastmap: Implement produce_free_peb()
Since 'commit f82290afc847 ("mtd: ubi: Fix worker handling")',
when booting from NAND, on a fresh NAND just after being flashed (and
only in this case), we got the following log:
ubi0: default fastmap pool size: 200
ubi0: default fastmap WL pool size: 100
ubi0: attaching mtd2
ubi0: scanning is finished
ubi0 error: ubi_update_fastmap: could not find any anchor PEB
ubi0 error: ubi_update_fastmap: could not find any anchor PEB
ubi0 error: ubi_wl_get_peb: Unable to get a free PEB from user WL pool
ubi0 error: autoresize: cannot auto-resize volume 1
UBI error: cannot attach mtd2UBI error: cannot initialize UBI, error
-28UBI init error 28
After analysis, in ubi_wl_init(), when performing schedule_erase(),
thread_enabled flag is not yet set to 1, which forbids ubi_do_worker()
to execute pending works.
This has to effect to not populate ubi->free with free physical
eraseblocks.
Following Richard Weinberger's advice, this patch has been
backported from kernel tree :
'commit 1cb8f9776c7d ("ubi: fastmap: Implement produce_free_peb()")'
