34 warnings. When you have that many, you might as well have none at all;
36 ones. For this reason, eliminating warnings is one of the highest-priority
41 Warnings issued by a compiler for C code can often be dismissed as false
43 Warnings from the documentation build almost always point at a real
44 problem; making those warnings go away requires understanding the problem
46 warnings should probably not say "fix a warning" in the changelog title;
49 Another important point is that documentation warnings are often created by

18 warnings:
77 RCU CPU stall warnings.
80 timeout down to just barely avoid RCU CPU stall warnings, and then
88 result in RCU CPU stall warnings for CONFIG_NO_HZ_COMMON=n kernels.
114 This resulted in a series of RCU CPU stall warnings, eventually
118 Note that SRCU does *not* have CPU stall warnings. Please note that
120 No grace period, no CPU stall warnings.
124 If you have a series of stall warnings from a single extended stall,
198 own warnings, as this often gives better-quality stack traces.
