The functions cp and kjournald were blocked in did vary, but\nkmirrord\u0027s wchan always pointed to \u0027mempool_alloc()\u0027. We\u0027ve seen this pattern\non 2.6.15 and 2.6.17 kernels. http://lkml.org/lkml/2005/4/20/142 indicates\nthat this problem has been around even before.\n\nSo much for the facts, here\u0027s my interpretation: mempool_alloc() first tries\nto atomically allocate the requested memory, or falls back to hand out\npreallocated chunks from the mempool. If both fail, it puts the calling\nprocess (kmirrord in this case) on a private waitqueue until somebody refills\nthe pool. Where the only \u0027somebody\u0027 is kmirrord itself, so we have a\ndeadlock.\n\nI worked around this problem by falling back to a (blocking) kmalloc when\nbefore kmirrord would have ended up on the waitqueue. This defeats part of\nthe benefits of using the mempool, but at least keeps the system running. And\nit could be done with a two-line change. Note that mempool_alloc() clears the\nGFP_NOIO flag internally, and only uses it to decide whether to wait or return\nan error if immediate allocation fails, so the attached patch doesn\u0027t change\nbehaviour in the non-deadlocking case. Path is against current git\n(2.6.18-rc4), but should apply to earlier versions as well.

I don\u0027t believe this is a supportable\napproach.\n\nThis patch changes the approach to use the same approach as swap files. i.e.\nbmap is used to enumerate all the block address of parts of the file and we\nwrite directly to those blocks of the device.\n\nswapfile only uses parts of the file that provide a full pages at contiguous\naddresses. We don\u0027t have that luxury so we have to cope with pages that are\nnon-contiguous in storage. To handle this we attach buffers to each page, and\nstore the addresses in those buffers.\n\nWith this approach the pagecache may contain data which is inconsistent with\nwhat is on disk. To alleviate the problems this can cause, md invalidates the\npagecache when releasing the file. If the file is to be examined while the\narray is active (a non-critical but occasionally useful function), O_DIRECT io\nmust be used. And new version of mdadm will have support for this.\n\nThis approach simplifies a lot of code:\n - we no longer need to keep a list of pages which we need to wait for,\n as the b_endio function can keep track of how many outstanding\n writes there are.
