Subject: ceph: make ceph_setxattr() and ceph_removexattr() more alike
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=18fa8b3feaac772925263b04b1429d80e2dfd779;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

ceph: make ceph_setxattr() and ceph_removexattr() more alike

This patch just rearranges a few bits of code to make more
portions of ceph_setxattr() and ceph_removexattr() identical.
