From: Boaz Harrosh Date: Mon, 7 Feb 2011 16:12:15 +0000 (+0200) Subject: exofs: deprecate the commands pending counter X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=a49fb4c3d035ab516507b31ec3bd49263caee14d;p=linux-beck.git exofs: deprecate the commands pending counter One leftover from the days of IBM's original code, is an SB counter that counts in-flight asynchronous commands. And a piece of code that waits for the counter to reach zero at unmount. I guess it might have been needed then, cause of some reference missing or something. I'm not removing it yet but am putting a warning message if ever this counter triggers at unmount. If I'll never see it triggers or reported I'll remove the counter for good. (I had this print as a debug output for a long time and never had it trigger) Signed-off-by: Boaz Harrosh --- diff --git a/fs/exofs/super.c b/fs/exofs/super.c index 5eb0851e5481..06065bd37fc3 100644 --- a/fs/exofs/super.c +++ b/fs/exofs/super.c @@ -409,6 +409,10 @@ static void exofs_put_super(struct super_block *sb) for (num_pend = atomic_read(&sbi->s_curr_pending); num_pend > 0; num_pend = atomic_read(&sbi->s_curr_pending)) { wait_queue_head_t wq; + + printk(KERN_NOTICE "%s: !!Pending operations in flight.
