Subject: staging/lustre: don't compile procfs code when CONFIG_PROC_FS is off
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=2c185ffa270a95e3699c223a0ee67f560ec0db8c;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

staging/lustre: don't compile procfs code when CONFIG_PROC_FS is off

The patch changes to conditionally compile procfs related source files.
This includes lproc_fid.c, lproc_fld.c, lproc_lov.c, lvfs_lib.c, lproc_mdc.c,
lproc_mgc.c, lprocfs_status.c, lproc_osc.c and sec_lproc.c.

There is a checkpatch warning about usage of simple_strtoul() in the patch.
But it needs to be fixed in a separate patch because it is not related to
CONFIG_PROC_FS breakage here.
