Hi, I am trying to do file write operations in a thread (filewrite()) initiated from a jprobe (fs_vfs_write()) set on kernel function (vfs_write()). Although the write operation succeed, I get this on my log:
BUG: sleeping function called from invalid context at kernel/sched.c:3678 in_atomic():0, irqs_disabled():1 [<c011a65b>] __might_sleep+0xa5/0xab [<c0343a00>] wait_for_completion+0x1a/0xc9 [<c0118480>] __wake_up+0x32/0x43 [<c012b33a>] __queue_work+0x42/0x4f [<c012e0f7>] kthread_create+0x9b/0xd3 [<c012e00a>] keventd_create_kthread+0x0/0x52 [<f8a560d4>] filewrite+0x0/0xaf [fsTrace] [<c03464b9>] do_page_fault+0x31f/0x5c5 [<f8a561da>] fs_vfs_write+0x57/0x9e [fsTrace] [<f8a560d4>] filewrite+0x0/0xaf [fsTrace] [<c015f396>] sys_write+0x41/0x67 [<c01034d1>] sysenter_past_esp+0x56/0x79 ======================= $ uname -a Linux cluster3 2.6.19.1 #1 SMP Thu Dec 21 14:03:57 EST 2006 i686 athlon i386 GNU/Linux I remember seeing something similar here on LKML, but am unable to trace it right now. Any idea what's going wrong?
