Don't populate the read-only array descs on the stack but instead it
static and add extra const. Also makes the object code smaller by 66
bytes:

Currently there is an error check on r that immediately returns
on an error rather than taking the error clean-up exit path via
label 'error'. Fix this to avoid resource leaks.

The continue statement at the end of a for-loop has no effect,
remove it.

In the case where recursing(mm) is true variable r2 is not
inintialized and an uninitialized value is being used in the

The variable index is being initialized with a value that is never read,
it is being updated later on. The assignment is redundant and can be
removed.

The call to lower_bound can return -1 if the key is not found
with the bsearch, leading to a negative index access into
array node->keys[]. Ensure this cannot occur by checking for
a negative index before reading from the array.

Currently if an xa_insert fails then there is a memory lead of the
recently allocated zone object. Fix this by kfree'ing zone before
returning on the error return path.

Variable block is an unsigned long long hence the less than zero

Currently, the -EFBIG error condition when n_bitmaps_bits is
too large is falling through to the next statement and the
error assignment to r is potentially being ignored. The code
should be exiting to the error path via label 'bad'. Fix
this by adding the missing goto state

currently there is no kmalloc failure check on the allocation of
the background_tracker struct variable b, and so a null return
will lead to a null pointer deference error. Add null check and move
