Do you have the RHEL6.1 kernel sources handy?
I just grabbed the particular kernel package'es source-package, installed it into ~/rpmbuild and ran "rpmbuild -bp" on its spec-file which should result in all RHs patches to be applied.
From the resulting code in ~/rpmbuild/BUILD/..., I grabbed file.c and placed it here:
http://troels.arvin.dk/misc/fio/unaligned/ Lines close to the error message (probably wrapped by my mailer): /* Unaligned direct AIO must be serialized; see comment above */ if (unaligned_aio) { static unsigned long unaligned_warn_time; /* Warn about this once per day */ if (printk_timed_ratelimit(&unaligned_warn_time, 60*60*24*HZ)) ext4_msg(inode->i_sb, KERN_WARNING, "Unaligned AIO/DIO on inode %ld by %s; " "performance will be poor.", inode->i_ino, current->comm); mutex_lock(&EXT4_I(inode)->i_aio_mutex); ext4_aiodio_wait(inode); } -- Regards, Troels Arvin <troels@xxxxxxxx> http://troels.arvin.dk/ -- To unsubscribe from this list: send the line "unsubscribe fio" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
