Delay struct net freeing while there's a sysfs instance refering to it

2011-06-12T21:45:41Z

* new refcount in struct net, controlling actual freeing of the memory * new method in kobj_ns_type_operations (->drop_ns()) * ->current_ns() semantics change - it's supposed to be followed by corresponding ->drop_ns(). For struct net in case of CONFIG_NET_NS it bumps the new refcount; net_drop_ns() decrements it and calls net_free() if the last reference has been dropped. Method renamed to ->grab_current_ns(). * old net_free() callers call net_drop_ns() instead. * sysfs_exit_ns() is gone, along with a large part of callchain leading to it; now that the references stored in ->ns[...] stay valid we do not need to hunt them down and replace them with NULL. That fixes problems in sysfs_lookup() and sysfs_readdir(), along with getting rid of sb->s_instances abuse. Note that struct net *shutdown* logics has not changed - net_cleanup() is called exactly when it used to be called. The only thing postponed by having a sysfs instance refering to that struct net is actual freeing of memory occupied by struct net. Signed-off-by: Al Viro

Merge branch 'stable/xen-swiotlb.bugfix' of git://git.kernel.org/pub/scm/linux/kernel/git/konrad/swiotlb-2.6

* 'stable/xen-swiotlb.bugfix' of git://git.kernel.org/pub/scm/linux/kernel/git/konrad/swiotlb-2.6: swiotlb: Export swioltb_nr_tbl and utilize it as appropiate.

vsprintf: Update %pI6c to not compress a single 0

2011-06-09T19:51:15Z

RFC 5952 (http://tools.ietf.org/html/rfc5952) mandates that 2 or more consecutive 0's are required before using :: compression. Update ip6_compressed_string to match the RFC and update the http reference as well. Signed-off-by: Joe Perches Signed-off-by: Linus Torvalds

swiotlb: Export swioltb_nr_tbl and utilize it as appropiate.

2011-06-06T19:41:16Z

By default the io_tlb_nslabs is set to zero, and gets set to whatever value is passed in via swiotlb_init_with_tbl function. The default value passed in is 64MB. However, if the user provides the 'swiotlb=' the default value is ignored and the value provided by the user is used... Except when the SWIOTLB is used under Xen - there the default value of 64MB is used and the Xen-SWIOTLB has no mechanism to get the 'io_tlb_nslabs' filled out by setup_io_tlb_npages functions. This patch provides a function for the Xen-SWIOTLB to call to see if the io_tlb_nslabs is set and if so use that value. Signed-off-by: FUJITA Tomonori Signed-off-by: Konrad Rzeszutek Wilk

arch: remove CONFIG_GENERIC_FIND_{NEXT_BIT,BIT_LE,LAST_BIT}

2011-05-27T00:12:38Z

By the previous style change, CONFIG_GENERIC_FIND_NEXT_BIT, CONFIG_GENERIC_FIND_BIT_LE, and CONFIG_GENERIC_FIND_LAST_BIT are not used to test for existence of find bitops anymore.

bitops: add #ifndef for each of find bitops

2011-05-27T00:12:38Z

The style that we normally use in asm-generic is to test the macro itself for existence, so in asm-generic, do: #ifndef find_next_zero_bit_le extern unsigned long find_next_zero_bit_le(const void *addr, unsigned long size, unsigned long offset); #endif and in the architectures, write static inline unsigned long find_next_zero_bit_le(const void *addr, unsigned long size, unsigned long offset) #define find_next_zero_bit_le find_next_zero_bit_le This adds the #ifndef for each of the find bitops in the generic header and source files.
