Chao Yu 50e1f8d221 f2fs: avoid to access NULL pointer in issue_flush_thread ... Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=75861 Denis 2014-05-10 11:28:59 UTC reported: "F2FS-fs (mmcblk0p28): mounting.. Unable to handle kernel NULL pointer dereference at virtual address 00000018 ... [<c0a2f678>] (_raw_spin_lock+0x3c/0x70) from [<c03a0330>] (issue_flush_thread+0x50/0x17c) [<c03a0330>] (issue_flush_thread+0x50/0x17c) from [<c01b4064>] (kthread+0x98/0xa4) [<c01b4064>] (kthread+0x98/0xa4) from [<c0108060>] (kernel_thread_exit+0x0/0x8)" This patch assign cmd_control_info in sm_info before issue_flush_thread is being created, so this make sure that issue flush thread will have no chance to access invalid info in fcc.
