Subject: KEYS: Don't return EAGAIN to keyctl_assume_authority()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=4d67431f80b1b822f0286afc9123ee453eac7334;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

KEYS: Don't return EAGAIN to keyctl_assume_authority()

Don't return EAGAIN to keyctl_assume_authority() to indicate that a key could
not be found (ENOKEY is only returned if a negative key is found).  Instead
return ENOKEY in both cases.
