      "message": "[PATCH] md/bitmap: change md/bitmap file handling to use bmap to file blocks\n\nIf md is asked to store a bitmap in a file, it tries to hold onto the page\ncache pages for that file, manipulate them directly, and call a cocktail of\noperations to write the file out.  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.  This saves a mempool.\n - -EAGAIN returns from write_page are no longer possible (not sure if\n    they ever were actually).\n\nSigned-off-by: Neil Brown \u003cneilb@suse.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"

This will usually clear the flags fairly quickly.\n\nIf writing the superblock finds that BIO_RW_BARRIER is -ENOTSUPP, we need to\nresubmit, so introduce function \"md_super_wait\" which waits for requests to\nfinish, and retries ENOTSUPP requests without the barrier flag.\n\nWhen writing the real raid1, write requests which were BIO_RW_BARRIER but\nwhich aresn\u0027t supported need to be retried.  So raid1d is enhanced to do this,\nand when any bio write completes (i.e.  no retry needed) we remove it from the\nr1bio, so that devices needing retry are easy to find.\n\nWe should hardly ever get -ENOTSUPP errors when writing data to the raid.\nIt should only happen if:\n  1/ the device used to support BARRIER, but now doesn\u0027t.

This is not implemented in\nthis patch.\n\nCurrently the bitmap is stored in a file which must (obviously) be stored on a\nseparate device.\n\nThe patch only provided infrastructure.
