UBI: introduce helpers dbg_chk_{io, gen}

2013-02-22T07:51:35+00:00

With this patch code is a bit more readable and there's no
generated code or functionality impact.
Furthermore, this abstracts implementation details and
will allow to change ubi_debug_info in a less invasive way.

UBI: do not allocate the memory unnecessarily

2013-02-22T07:51:34+00:00

UBI reserves an LEB sized buffer for various needs. We can use this buffer
while scanning, instead of allocating another one. This patch was originally
created by Jan Luebbe , but then he dropped it and I picked
up and tweaked a little bit.

- Export compare_lebs() as fastmap needs this function.
- Implement fastmap scan logic.

UBI: print less

2012-10-05T11:22:31+00:00

UBI currently prints a lot of information when it mounts a volume, which
bothers some people. Make it less chatty - print only important information
by default.

Get rid of 'dbg_msg()' macro completely.

UBI: use pr_ helper instead of printk

2012-10-05T11:22:31+00:00

Use 'pr_err()' instead of 'printk(KERN_ERR', etc.

UBI: comply with coding style

2012-10-05T11:22:31+00:00

Join all the split printk lines in order to stop checkpatch complaining.

UBI: erase free PEB with bitflip in EC header

2012-10-05T11:22:05+00:00

Without this patch, these PEB are not scrubbed until we put data in them.
Bitflip can accumulate latter and we can loose the EC header (but VID header
should be intact and allow to recover data).

UBI: add volume id struct ubi_ainf_peb

2012-05-23T10:04:37+00:00

This patch adds the volume id to struct ubi_ainf_peb when scanning the LEBs at
startup. PEBs now added to the erase queue will know their original LEB number
and volume id, if available, and will be -1 otherwise (for instance, if the VID
header is unreadable).

This was tested by creating an ubi device with 3 volumes and disabiling the
ubi_thread's do_work functionality. The different ubi volumes were formatted
to ubifs and had files created and erased.  The ubi modules was reloaded and
the list of LEB's added to the erased list was outputted, confirming the
volume ids and LEB numbers were appropriate.

UBI: rename scan.c to attach.c

2012-05-23T10:04:37+00:00

Finally, rename the scan.c file. Now adding fastmap support won't look that
hacky anymore.
