Note: currently almost all instances of address_space methods are

and pass foo_get_block() as a callback (on local block-based filesystems,

indeed). BKL is not needed for library stuff and is usually taken by

foo_get_block(). It's an overkill, since block bitmaps can be protected by

internal fs locking and real critical areas are much smaller than the areas

|

The kernel memory allocator divides physically contiguous memory
|
||||
blocks into "zones", where each zone is a power of two number of
|
||||
pages. This option selects the largest power of two that the kernel
|
||||
keeps in the memory allocator. If you need to allocate very large
|
||||
blocks of physically contiguous memory, then you may need to
|
||||
increase this value.
|
||||
|
||||
This config option is actually maximum order plus one. For example,
|
||||
a value of 11 means that the largest free memory block is 2^10 pages.
|
||||
|
||||
The page size is not necessarily 4KB. Keep this in mind
|
||||
when choosing a value for this option.
