Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace
Pull pid allocation bug fix from Eric Biederman: "The replacement of the pid hash table and the pid bitmap with an idr resulted in an implementation that now fails more often in low memory situations. Allowing fuzzers to observe bad behavior from a memory allocation failure during pid allocation. This is a small change to fix this by making the kernel more robust in the case of error. The non-error paths are left alone so the only danger is to the already broken error path. I have manually injected errors and verified that this new error handling works" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: pid: Handle failure to allocate the first pid in a pid namespace
