process_reloc_for_got: no ENOMEM check
Hi, I've found in ./arch/alpha/kernel/module.c in process_reloc_for_got() such code: g = kmalloc (sizeof (*g), GFP_KERNEL); g->next = chains[r_sym].next; g->r_addend = r_addend; g->got_offset = *poffset; Here we use 'g' without checking it for zero. I don't know what this func... 16 Jul 2010 06:38

Where system interrupts get disabled at LAPIC timer handler execution?
Dear all, I am trying to demystify what happens when the kernel has configured to use LAPIC timer as its timer and I've ran into some problems/questions. AFAIK, when a LAPIC timer interrupt occurs, the assembly wrapper at enrty_32.s jumps the execution at smp_apic_timer_interrupt(). At the beginning of this fu... 16 Jul 2010 06:38
[PATCH] twl6040: fix wrong kfree in twl6040_remove and twl6040_codec_remove
Memory allocation part: We allocate a memory in twl6040_codec_probe(): priv = kzalloc(sizeof(struct twl6040_data), GFP_KERNEL); twl6040_codec = codec = &priv->codec; Memory release part: In twl6040_codec_remove() we should kfree(priv) instead of kfree(twl6040_codec). In twl6040_remove(), no need... 16 Jul 2010 05:33
[PATCH] [RFC] CFQ: Make prio_trees per cfq group basis to improve IO performance
Currently, prio_trees is global, and we rely on cfqq_close() to search a coorperator. If the returned cfqq and the active cfqq don't belong to the same group, coorperator searching fails. Actually, that's not the case. Even if cfqq_close() returns a cfqq which belong to another cfq group, it's still likely that a ... 16 Jul 2010 05:33
