From 83a75e3f14667b334ecd53b6334407ace8679eed Mon Sep 17 00:00:00 2001 From: Sandhya Bankar Date: Sun, 18 Sep 2016 05:23:49 +0530 Subject: [PATCH] Staging: lustre: Convert array index from the loop bound to the loop index. Convert array index from the loop bound to the loop index. The structure cl_env_percpu[NR_CPUS] has been initializing for each possible cpu (i.e 0 to i). During initialization if any error will occurred, the error handling code should uninitialize cl_env_percpu upto i. But currently unitialization is repeatedly done for the same cl_env_percpu[i] element. This does not seems to be correct. Used below semantic patch to identify this issue: @@ expression e1,e2,ar; @@ for(e1 = 0; e1 < e2; e1++) { <... ar[ - e2 + e1 ] ...> } Signed-off-by: Sandhya Bankar Signed-off-by: Greg Kroah-Hartman --- drivers/staging/lustre/lustre/obdclass/cl_object.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/staging/lustre/lustre/obdclass/cl_object.c b/drivers/staging/lustre/lustre/obdclass/cl_object.c index e493c80..3199dd4 100644 --- a/drivers/staging/lustre/lustre/obdclass/cl_object.c +++ b/drivers/staging/lustre/lustre/obdclass/cl_object.c @@ -1022,7 +1022,7 @@ static int cl_env_percpu_init(void) * thus we must uninitialize up to i, the rest are undefined. */ for (j = 0; j < i; j++) { - cle = &cl_env_percpu[i]; + cle = &cl_env_percpu[j]; lu_context_exit(&cle->ce_ses); lu_context_fini(&cle->ce_ses); lu_env_fini(&cle->ce_lu); -- 2.7.4
