--- Comment #59 from Ralf Müller
(In reply to Holger Schranz from comment #57)
Hello @ all,
after some times now I can say it runs more stable than before with proposal of a fix from Ralf.
A similar issue occured after an timeout onto a connection after 500 sec.. A very rare situation.
How to continue with this issue now? What about the proposal for a fix from Ralf?
Ralf, can you please send to patch upstream (to the linux-scsi mailing-list the open-fcoe list is defunct).
Hi Johannes, sorry for the long delay ... First, the modification: diff /usr/src/linux-4.4.114-42/drivers/scsi/fcoe/fcoe_ctlr.c fcoe_ctlr.c 2179c2179 < rcu_read_lock(); ---
mutex_lock(&lport->disc.disc_mutex);
2186,2187d2185 < rcu_read_unlock(); < mutex_lock(&lport->disc.disc_mutex); 2717c2715 < rcu_read_lock(); ---
mutex_lock(&lport->disc.disc_mutex);
2738c2736 < rcu_read_unlock(); ---
mutex_unlock(&lport->disc.disc_mutex);
3085,3086d3082 < mutex_unlock(&disc->disc_mutex); < rcu_read_lock(); 3095c3091 < rcu_read_unlock(); ---
mutex_unlock(&disc->disc_mutex);
Second: I have no idea what you mean with 'can you please send to patch upstream ... ' Can you explain what i should do, please -- You are receiving this mail because: You are on the CC list for the bug.
