[Ocfs2-devel] [PATCH] ocfs2: Update atime in splice read if necessary.

[Ocfs2-devel] [PATCH] ocfs2: Update atime in splice read if necessary.

[Tao Ma]

We should call ocfs2_inode_lock_atime instead of ocfs2_inode_lock
in ocfs2_file_splice_read like we do in ocfs2_file_aio_read so
that we can update atime in splice read if necessary.
