Merge tag 'upstream-3.7-rc1-fastmap' of git://git.infradead.org/linux-ubi
Pull UBI fastmap changes from Artem Bityutskiy: "This pull request contains the UBI fastmap support implemented by Richard Weinberger from Linutronix. Fastmap is designed to address UBI's slow scanning issues. Namely, it introduces a new on-flash data-structure called "fastmap", which stores the information about logical<->physical eraseblocks mappings. So now to get this information just read the fastmap, instead of doing full scan. More information here can be found in Richard's announcement in LKML (Subject: UBI: Fastmap request for inclusion (v19)): http://thread.gmane.org/gmane.linux.kernel/1364922/focus=1369109 One thing I want to explicitly say is that fastmap did not have large enough linux-next exposure. It is partially my fault - I did not respond quickly enough. I _really_ apologize for this. But it had good testing and disabled by default, so I do not expect that we'll break anything. Fastmap is declared as experimental so far, and it is off by default. We did declare that the on-flash format may be changed. The reason for this is that no one used it in real production so far, so there is a high risk that something is missing. Besides, we do not have user-space tools supporting fastmap so far. Nevertheless, I suggest we merge this feature. Many people want UBI's scanning bottleneck to be fixed and merging fastmap now should accelerate its production use. The plan is to make it bullet-prove, somewhat clean-up, and make it the default for UBI. I do not know how many kernel releases will it take. Basically, I what I want to do for fastmap is something like Linus did for btrfs few years ago." * tag 'upstream-3.7-rc1-fastmap' of git://git.infradead.org/linux-ubi: UBI: Wire-up fastmap UBI: Add fastmap core UBI: Add fastmap support to the WL sub-system UBI: Add fastmap stuff to attach.c UBI: Wire-up ->fm_sem UBI: Add fastmap bits to build.c UBI: Add self_check_eba() UBI: Export next_sqnum() UBI: Add fastmap stuff to ubi.h UBI: Add fastmap on-flash data structures
