ida: Start new test_ida module Start transitioning the IDA tests into kernel space. Framework heavily cribbed from test_xarray.c. Signed-off-by: Matthew Wilcox <willy@infradead.org>

test_ida: check_ida_destroy and check_ida_alloc Move these tests from the userspace test-suite to the kernel test-suite. Also convert check_ida_random to the new API. Signed-off-by: Matthew Wilcox <willy@infradead.org>
2018-06-18 18:39:28 -04:00
test_ida: Move ida_check_leaf Convert to new API and move to kernel space. Take the opportunity to test the situation a little more thoroughly (ie at different offsets). Signed-off-by: Matthew Wilcox <willy@infradead.org>

test_ida: Move ida_check_max Convert to new API and move to kernel space. Signed-off-by: Matthew Wilcox <willy@infradead.org>

test_ida: Convert check_ida_conv to new API Move as much as possible to kernel space; leave the parts in user space that rely on checking memory allocation failures to detect the transition between an exceptional entry and a bitmap. Signed-off-by: Matthew Wilcox <willy@infradead.org>

ida: Fix crash in ida_free when the bitmap is empty The IDA usually detects double-frees, but that detection failed to consider the case when there are no nearby IDs allocated and so we have a NULL bitmap rather than simply having a clear bit. Add some tests to the test-suite to be sure we don't inadvertently reintroduce this problem. Unfortunately they're quite noisy so include a message to disregard the warnings.

test_ida: Fix lockdep warning The IDA was declared on the stack instead of statically, so lockdep triggered a warning that it was improperly initialised. Reported-by: 0day bot Tested-by: Rong Chen <rong.a.chen@intel.com> Signed-off-by: Matthew Wilcox <willy@infradead.org>
