Subject: ubifs: another scheduling while atomic back trace
Date: Thu, 18 Dec 2008 08:34:54 -0500 [thread overview]
Message-ID: <494A517E.2000405@runbox.com> (raw)
I tracked it down to fs/ubifs/journal.c in make_reservation()?
the code is:
again:
down_read()
err = reserve_space()
if ( !err) return 0
up_read()
shouldn't we to the up as part of the if? ie
if ( !err ) { up_read(); return 0; };
Also, I notice fs/fs-writeback.c in writeback_inodes does a
down_read_trylock. Won't this interfear with the down_read above?
