Subject: NFS: Eliminate nfs_renew_times()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=77a55a1fe8f26f7d022986a599b68002e21d968a;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

NFS: Eliminate nfs_renew_times()

The nfs_renew_times() function plants the current time in jiffies in
dentry->d_time.  But a call to nfs_renew_times() is always followed by
another call that overwrites dentry->d_time.  Get rid of the
nfs_renew_times() calls.
