From 9a58a80a701bdb2d220cdab4914218df5b48d781 Mon Sep 17 00:00:00 2001 From: Alexey Dobriyan Date: Thu, 14 Jan 2010 03:10:54 -0800 Subject: proc_fops: convert drivers/isdn/ to seq_file Convert code away from ->read_proc/->write_proc interfaces. Switch to proc_create()/proc_create_data() which make addition of proc entries reliable wrt NULL ->proc_fops, NULL ->data and so on. Problem with ->read_proc et al is described here commit 786d7e1612f0b0adb6046f19b906609e4fe8b1ba "Fix rmmod/read/write races in /proc entries" [akpm@linux-foundation.org: CONFIG_PROC_FS=n build fix] Signed-off-by: Alexey Dobriyan Signed-off-by: Tilman Schmidt Signed-off-by: Karsten Keil Signed-off-by: David S.
