[PATCH] Fixed a mismatch between the users of radix_tree and the implementation. This matters for the lockless page cache, in particular find_get_pages implementation. In the following case, we get can get a deadlock: 0. The radix tree contains two items, one has the index 0. 1. The reader (in this case find_get_pages) takes the rcu_read_lock. 2. The reader acquires slot(s) f... 13 Aug 2010 03:50

[PATCH] kvm: fix poison overwritten caused by using wrong xstate size fpu.state is allocated from task_xstate_cachep, the size of task_xstate_cachep is xstate_size. xstate_size is set from cpuid instruction, which is often smaller than sizeof(struct xsave_struct). kvm is using sizeof(struct xsave_struct) to fill in/out fpu.state.xsave, as what we allocated for fpu.state is xstate_siz... 13 Aug 2010 03:50

[Resend][Patch v2] kexec: increase max of kexec segments and use dynamic allocation Currently KEXEC_SEGMENT_MAX is only 16 which is too small for machine with many memory ranges. When hibernate on a machine with disjoint memory we do need one segment for each memory region. Increase this hard limit to 16K which is reasonably large. And change ->segment from a static array to a dynamically all... 13 Aug 2010 01:41 |
