ida: make 'ida_dump' static Patch series "Treewide: enable -Wmissing-prototypes", v3. At this point, there are five architectures with a number of known regressions: alpha, nios2, mips, sh and sparc. In the previous version of this patch, I had turned off the missing prototype warnings for the 15 architectures that still had issues, but since there are only five left, I think we can leave the rest to the maintainers (Cc'd here) as well. The series is also likely to cause occasional build regressions on linux-next as developers add new code that misses prototypes. Hopefully this should be resolved by the time the patches make it into a release and everyone gets the warnings right away. This patch (of 6): There is no global declaration for ida_dump() and no other callers, so make it static to avoid this warning: lib/test_ida.c:16:6: error: no previous prototype for 'ida_dump' Link: https://lkml.kernel.org/r/20231123110506.707903-1-arnd@kernel.org Link: https://lkml.kernel.org/r/20231123110506.707903-2-arnd@kernel.org Fixes: 8ab8ba38d488 ("ida: Start new test_ida module") Signed-off-by: Arnd Bergmann <arnd@arndb.de> Cc: "David S.

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.
