From 52f993b8e89487ec9ee15a7fb4979e0f09a45b27 Mon Sep 17 00:00:00 2001 From: Yunhong Jiang Date: Wed, 8 Mar 2017 23:13:28 -0800 Subject: Upgrade to 4.4.50-rt62 The current kernel is based on rt kernel v4.4.6-rt14. We will upgrade it to 4.4.50-rt62. The command to achieve it is: a) Clone a git repo from git://git.kernel.org/pub/scm/linux/kernel/git/rt/linux-stable-rt.git b) Get the diff between this two changesets: git diff 640eca2901f3435e616157b11379d3223a44b391 705619beeea1b0b48219a683fd1a901a86fdaf5e where the two commits are: [yjiang5@jnakajim-build linux-stable-rt]$ git show --oneline --name-only 640eca2901f3435e616157b11379d3223a44b391 640eca2901f3 v4.4.6-rt14 localversion-rt [yjiang5@jnakajim-build linux-stable-rt]$ git show --oneline --name-only 705619beeea1b0b48219a683fd1a901a86fdaf5e 705619beeea1 Linux 4.4.50-rt62 localversion-rt c) One patch has been backported thus revert the patch before applying. filterdiff -p1 -x scripts/package/Makefile ~/tmp/v4.4.6-rt14-4.4.50-rt62.diff |patch -p1 --dry-run Upstream status: backport Change-Id: I244d57a32f6066e5a5b9915f9fbf99e7bbca6e01 Signed-off-by: Yunhong Jiang --- kernel/fs/xfs/libxfs/xfs_alloc.c | 2 ++ kernel/fs/xfs/libxfs/xfs_alloc_btree.c | 1 + kernel/fs/xfs/libxfs/xfs_attr_leaf.c | 1 + kernel/fs/xfs/libxfs/xfs_attr_remote.c | 1 + kernel/fs/xfs/libxfs/xfs_bmap_btree.c | 1 + kernel/fs/xfs/libxfs/xfs_da_btree.c | 1 + kernel/fs/xfs/libxfs/xfs_dir2_block.c | 1 + kernel/fs/xfs/libxfs/xfs_dir2_data.c | 2 ++ kernel/fs/xfs/libxfs/xfs_dir2_leaf.c | 2 ++ kernel/fs/xfs/libxfs/xfs_dir2_node.c | 1 + kernel/fs/xfs/libxfs/xfs_dquot_buf.c | 40 ++++++++++++++++++++++++------- kernel/fs/xfs/libxfs/xfs_ialloc.c | 1 + kernel/fs/xfs/libxfs/xfs_ialloc_btree.c | 1 + kernel/fs/xfs/libxfs/xfs_inode_buf.c | 4 ++++ kernel/fs/xfs/libxfs/xfs_quota_defs.h | 2 +- kernel/fs/xfs/libxfs/xfs_sb.c | 5 +++- kernel/fs/xfs/libxfs/xfs_shared.h | 1 + kernel/fs/xfs/libxfs/xfs_symlink_remote.c | 1 + 18 files changed, 58 insertions(+), 10 deletions(-) (limited to 'kernel/fs/xfs/libxfs') diff --git a/kernel/fs/xfs/libxfs/xfs_alloc.c b/kernel/fs/xfs/libxfs/xfs_alloc.c index 3479294c1..e1e7fe3b5 100644 --- a/kernel/fs/xfs/libxfs/xfs_alloc.c +++ b/kernel/fs/xfs/libxfs/xfs_alloc.c @@ -535,6 +535,7 @@ xfs_agfl_write_verify( } const struct xfs_buf_ops xfs_agfl_buf_ops = { + .name = "xfs_agfl", .verify_read = xfs_agfl_read_verify, .verify_write = xfs_agfl_write_verify, };
