UBI: power cut emulation for testing

2015-04-13T19:05:17+00:00

Emulate random power cuts by switching device to ro after a number of
writes to allow simple power cut testing with nand-sim.

Maximum and minimum number of successful writes before power cut and
what kind of writes (EC header, VID header or none) to interrupt
configurable via debugfs.

UBI: Fastmap: Add new module parameter fm_debug

2015-03-26T21:46:06+00:00

If fm_debug is set fastmap debugging is enabled by default.
This is useful if one wants to debug fastmap on an UBI device
with serves the rootfs.
The the UBI attach mechanism runs long before debugfs can be mounted
and chk_fastmap set.

UBI: embed ubi_debug_info field in ubi_device struct

2012-12-10T11:38:59+00:00

ubi_debug_info struct was dynamically allocated which
is always suboptimal, for it tends to fragment memory
and make the code error-prone.
Fix this by embedding it in ubi_device struct.

UBI: introduce helpers dbg_chk_{io, gen}

2012-12-10T11:38:59+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: print less

2012-09-04T06:39:02+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.
