[PATCH] mempool: use common mempool kmalloc allocator

2006-03-26T16:56:59+00:00

This patch changes several mempool users, all of which are basically just
wrappers around kmalloc(), to use the common mempool_kmalloc/kfree, rather
than their own wrapper function, removing a bunch of duplicated code.

[PATCH] md/bitmap.c:bitmap_mask_state(): fix inconsequent NULL checking

2006-03-25T16:22:57+00:00

We dereference bitmap both one line above and one line below this check
rendering this check quite useless.

Spotted by the Coverity checker.

BUG_ON() Conversion in md/bitmap.c

2006-03-24T17:35:26+00:00

this changes if() BUG(); constructs to BUG_ON() which is
cleaner and can better optimized away

[PATCH] Unlinline a bunch of other functions

2006-01-15T02:27:06+00:00

Remove the "inline" keyword from a bunch of big functions in the kernel with
the goal of shrinking it by 30kb to 40kb

[PATCH] md: make sure bitmap updates are visible through filesystem

2006-01-06T16:34:08+00:00

When we update a page_cache page in the kernel, we need to flush_dache_page or
userspace might not see the change.

[PATCH] md: define and use safe_put_page for md

2006-01-06T16:34:07+00:00

md sometimes call put_page on NULL pointers (treating it like kfree).  This is
not safe, so define and use a 'safe_put_page' which checks for NULL.

[PATCH] md: remove inappropriate limits in md/bitmap configuration.

2006-01-06T16:34:07+00:00

The kernel should not be imposing these policy limits: The time between
bitmap updates should certainly be allowed to be more than 15 seconds, and
if someone wants a bitmap chunk size in excess of 4MB, the kernel isn't the
place to stop them.
