From 97a32539b9568bb653683349e5a76d02ff3c3e2c Mon Sep 17 00:00:00 2001 From: Alexey Dobriyan Date: Mon, 3 Feb 2020 17:37:17 -0800 Subject: proc: convert everything to "struct proc_ops" The most notable change is DEFINE_SHOW_ATTRIBUTE macro split in seq_file.h. Conversion rule is: llseek => proc_lseek unlocked_ioctl => proc_ioctl xxx => proc_xxx delete ".owner = THIS_MODULE" line [akpm@linux-foundation.org: fix drivers/isdn/capi/kcapi_proc.c] [sfr@canb.auug.org.au: fix kernel/sched/psi.c] Link: http://lkml.kernel.org/r/20200122180545.36222f50@canb.auug.org.au Link: http://lkml.kernel.org/r/20191225172546.GB13378@avx2 Signed-off-by: Alexey Dobriyan Signed-off-by: Stephen Rothwell Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- fs/proc/cpuinfo.c | 12 ++++++------ fs/proc/kcore.c | 13 ++++++------- fs/proc/kmsg.c | 14 +++++++------- fs/proc/page.c | 24 ++++++++++++------------ fs/proc/stat.c | 12 ++++++------ fs/proc/vmcore.c | 10 +++++----- 6 files changed, 42 insertions(+), 43 deletions(-) (limited to 'fs/proc') diff --git a/fs/proc/cpuinfo.c b/fs/proc/cpuinfo.c index 96f1087e372c..c1dea9b8222e 100644 --- a/fs/proc/cpuinfo.c +++ b/fs/proc/cpuinfo.c @@ -16,16 +16,16 @@ static int cpuinfo_open(struct inode *inode, struct file *file) return seq_open(file, &cpuinfo_op);
