From 343fb6af089cc7afc4041556a1cc27029a8eb2a0 Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Tue, 9 Jan 2018 12:19:38 +1100 Subject: [PATCH] staging: lustre: Convert more LIBCFS_ALLOC allocation to direct GFP_KERNEL None of these need to be GFP_NOFS, so use GFP_KERNEL explicitly with kmalloc(), kvmalloc(), or kvmalloc_array(). Change matching LIBCFS_FREE() to kfree() or kvfree() Signed-off-by: NeilBrown Signed-off-by: Greg Kroah-Hartman --- .../lustre/lnet/libcfs/linux/linux-module.c | 4 +-- drivers/staging/lustre/lnet/libcfs/module.c | 9 +++--- drivers/staging/lustre/lnet/lnet/api-ni.c | 17 +++++------ drivers/staging/lustre/lnet/lnet/config.c | 34 +++++++++------------- 4 files changed, 26 insertions(+), 38 deletions(-) diff --git a/drivers/staging/lustre/lnet/libcfs/linux/linux-module.c b/drivers/staging/lustre/lnet/libcfs/linux/linux-module.c index b574623..ddf6256 100644 --- a/drivers/staging/lustre/lnet/libcfs/linux/linux-module.c +++ b/drivers/staging/lustre/lnet/libcfs/linux/linux-module.c @@ -146,7 +146,7 @@ int libcfs_ioctl_getdata(struct libcfs_ioctl_hdr **hdr_pp, return -EINVAL;
