... postponing assignments until they're needed. Doesn't change code size.

mqueue: remove unneeded info->messages initialization

... and abort earlier if we couldn't allocate the message pointers array,
avoiding the u->mq_bytes accounting logic.

nommu: fix SYSV SHM for NOMMU

2010-01-16T20:15:39+00:00

Commit c4caa778157dbbf04116f0ac2111e389b5cd7a29 ("file
->get_unmapped_area() shouldn't duplicate work of get_unmapped_area()")
broke SYSV SHM for NOMMU by taking away the pointer to
shm_get_unmapped_area() from shm_file_operations.

Put it back conditionally on CONFIG_MMU=n.

file->f_ops->get_unmapped_area() is used to find out the base address for a
mapping of a mappable chardev device or mappable memory-based file (such as a
ramfs file).  It needs to be called prior to file->f_ops->mmap() being called.

Untangling ima mess, part 2: deal with counters

2009-12-16T17:16:47+00:00

* do ima_get_count() in __dentry_open()
* stop doing that in followups
* move ima_path_check() to right after nameidata_to_filp()
* don't bump counters on it

Untangling ima mess, part 1: alloc_file()

2009-12-16T17:16:47+00:00

There are 2 groups of alloc_file() callers:
	* ones that are followed by ima_counts_get
	* ones giving non-regular files
So let's pull that ima_counts_get() into alloc_file();
it's a no-op in case of non-regular files.
