      UBI: fix warnings when debugging is enabled · ed45819f
      由 Artem Bityutskiy 提交于 
      The 'ubi_io_read_vid_hdr()' and 'ubi_io_read_ec_hdr()' function
have the 'verbose' argument which controls whether they should
print a warning if the VID/EC header was not found or was corrupted.
Some callers require the headers to be OK, and pass 1. Some allow
a corrupted/not present header, and pass 0.

       if (UBI_IO_DEBUG)
               verbose = 1;

And UBI_IO_DEBUG is 1 if CONFIG_MTD_UBI_DEBUG_MSG_BLD is true. So in
this case the warning is printed all the time. This confuses people.

Thus, do not print the messages as warnings if UBI_IO_DEBUG is true,
but print them as debugging messages instead.

      UBI: fix IS_ERR test · 0e4a008a
      由 Julien Brunel 提交于 
      In case of error, the function add_volume returns an ERR pointer. The
result of IS_ERR, which is supposed to be used in a test as it is, is
here checked to be less than zero, which seems odd. We suggest to
replace this test by a simple IS_ERR test.

A simplified version of the semantic match that finds this problem is
as follows:
(http://www.emn.fr/x-info/coccinelle/)

// <smpl>
@def0@
expression x;
position p0;
@@
x@p0 = add_volume(...)

@protected@
expression def0.x,E;
position def0.p0;
position p;
statement S;
@@
x@p0
... when != x = E
if (!IS_ERR(x) && ...) {<... x@p ...>} else S

@unprotected@
expression def0.x,E;
identifier fld;
position def0.p0;
position p != protected.p;
@@
x@p0
... when != x = E
* x@p->fld

      UBI: always start the background thread · d37e6bf6
      由 Artem Bityutskiy 提交于 
      This fix only affects UBI debugging.

If the the background thread is disabled for debugging purposes,
start it anyway, because otherwise we see tonns of kernel debugging
complaints like this:

INFO: task ubi_bgt0d:26857 blocked for more than 120 seconds.
"echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message.

 =======================

So start it, and go sleep inside it, instead of creating it and never
start.
