Pull tracing warning fix from Steven Rostedt: "Make the GCC 9 warning for sub struct memset go away. GCC 9 now warns about calling memset() on partial structures when it goes across multiple fields. This adds a helper for the place in tracing that does this type of clearing of a structure" * tag 'trace-v5.2-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: tracing: Silence GCC 9 array bounds warning

tracing: Silence GCC 9 array bounds warning

2019-05-26T03:04:30Z

Starting with GCC 9, -Warray-bounds detects cases when memset is called starting on a member of a struct but the size to be cleared ends up writing over further members. Such a call happens in the trace code to clear, at once, all members after and including `seq` on struct trace_iterator: In function 'memset', inlined from 'ftrace_dump' at kernel/trace/trace.c:8914:3: ./include/linux/string.h:344:9: warning: '__builtin_memset' offset [8505, 8560] from the object at 'iter' is out of the bounds of referenced subobject 'seq' with type 'struct trace_seq' at offset 4368 [-Warray-bounds] 344 | return __builtin_memset(p, c, size); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~ In order to avoid GCC complaining about it, we compute the address ourselves by adding the offsetof distance instead of referring directly to the member. Since there are two places doing this clear (trace.c and trace_kdb.c), take the chance to move the workaround into a single place in the internal header.

ext4: fix dcache lookup of !casefolded directories

2019-05-25T03:48:23Z

Found by visual inspection, this wasn't caught by my xfstest, since it's effect is ignoring positive dentries in the cache the fallback just goes to the disk. it was introduced in the last iteration of the case-insensitive patch. d_compare should return 0 when the entries match, so make sure we are correctly comparing the entire string if the encoding feature is set and we are on a case-INsensitive directory.
