From: Cong Ding <[email protected]> ------------------- This is a commit scheduled for the next v2.6.34 longterm release. http://git.kernel.org/?p=linux/kernel/git/paulg/longterm-queue-2.6.34.git If you see a problem with using this for longterm, please comment. -------------------
commit 10b8c7dff5d3633b69e77f57d404dab54ead3787 upstream. When it goes to error through line 144, the memory allocated to *devname is not freed, and the caller doesn't free it either in line 250. So we free the memroy of *devname in function cifs_compose_mount_options() when it goes to error.
