Subject: xfs: make several functions static
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0d5a75e9e23ee39cd0d8a167393dcedb4f0f47b2;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

xfs: make several functions static

Al Viro noticed that xfs_lock_inodes should be static, and
that led to ... a few more.

These are just the easy ones, others require moving functions
higher in source files, so that's not done here to keep
this review simple.
