Subject: ceph: drop extra open file reference in ceph_atomic_open()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ab866549b3da3eef88e51696bcb24e79f1cc3745;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

ceph: drop extra open file reference in ceph_atomic_open()

ceph_atomic_open() calls ceph_open() after receiving the MDS reply.
ceph_open() grabs an extra open file reference. (The open request
already holds an open file reference)
