Subject: ceph_fill_trace(): don't bother with d_instantiate(dn, NULL)
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f8b31710e46c852b2af1635d1b6fab8e69bf7799;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

ceph_fill_trace(): don't bother with d_instantiate(dn, NULL)

... and use d_add(dn, NULL) in case we need to hash a negative
unhashed rather than using d_rehash() directly.
