Hi,
i'm developing block layer workload simulator/player and need to
generate bios as close as possible to the ones in original workload.
To play workload i employ aio + O_DIRECT, but all IOs end up as bios
with SYNC flag set. So i wonder is there any way to control bios
flags from userspace or, m
Hi,
i noticed that loading null_blk with queue_mode=1 and irqmode=2 parameters
and slab poisoning enabled causes general protection fault:
[ 20.671974] general protection fault: [#1] SMP
[ 20.678050] Modules linked in: null_blk(+) usbhid hid psmouse floppy

The %*ph specifier allows to pass a pointer and length instead of
pushing each byte via stack. The patch converts code to use it.

Hello,

Hi,
option CONFIG_UBSAN_ALIGNMENT breaks x86-64 kernel with lockdep enabled,
i. e kernel with CONFIG_UBSAN_ALIGNMENT fails to load without even any
error message.
The problem is that ubsan callbacks use spinlocks and might be called
before lockdep is initialized. Particularly this line in the

The problem is that bio_check_pages_dirty calls bio_put, so we must
not access bio fields after bio_check_pages_dirty.

bio_put()").
