Re: [ANNOUNCE][PATCH 2.6] md: persistent (file-backed) bitmap and async writes

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



And here is the next set of patches. Tested thoroughly against
2.6.2-rc2-bk3 and compile tested against 2.6.3-rc2.

I've split the kernel code into two patches. The async write patch is
dependent on the bitmap patch. The bitmap patch includes the new
GET/SET_EXTRA_ARRAY_INFO ioctls and a mempool for the bitmap_update
structures (no more -ENOMEM in the I/O request path). 

bitmap patch vs. 2.6.3-rc2
--------------------------
http://parisc-linux.org/~jejb/md_bitmap/md_bitmap_2_30_2_6_3_RC2.diff 

async write patch vs. 2.6.3-rc2
-------------------------------
http://parisc-linux.org/~jejb/md_bitmap/md_async_2_30_2_6_3_RC2.diff

mdadm patch vs. 1.5.0
---------------------
http://parisc-linux.org/~jejb/md_bitmap/mdadm_1_5_0-2.diff


For simplicity's sake, the mdadm patch includes both the bitmap and
async code (it's a fairly small patch anyway, and probably wouldn't have
benefited much from a split).
