Subject: security/keys/keyctl.c: suppress memory allocation failure warning
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=4f1c28d241d0882f25112d494885cd6084db225b;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

security/keys/keyctl.c: suppress memory allocation failure warning

This allocation may be large.  The code is probing to see if it will
succeed and if not, it falls back to vmalloc().  We should suppress any
page-allocation failure messages when the fallback happens.
