Subject: Re: [syzbot] [netfs?] INFO: task hung in netfs_unbuffered_write_iter
Date: Fri, 28 Mar 2025 18:14:54 +0000	[thread overview]
Message-ID: <86991.1743185694@warthog.procyon.org.uk> (raw)

#syz test: git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs.git netfs-fixes

  There's inconsistency with some wakeups between using rreq->waitq (a private
  waitqueue) and using clear_and_wake_up_bit() (a shared global waitqueue).
  The reason I didn't get round to posting the patches on this branch yet is
  that they *ought* to fix the problem, but Steve French still sees an
  occasional hang with cifs - but only in his automated testing thing, and we
  haven't tracked it down yet.

  David
