The new, more efficient writing function can\nbe used via the mount option mblk_io_submit, so we can test and fix\nthe new page I/O code.\n\nTo reproduce the problem, install postgres 8.4 or 9.0, and pin enough\nmemory such that the system just at the end of triggering writeback\nbefore running the following sql script:\n\nbegin;\ncreate temporary table foo as select x as a, ARRAY[x] as b FROM\ngenerate_series(1, 10000000 ) AS x;\ncreate index foo_a_idx on foo (a);\ncreate index foo_b_idx on foo USING GIN (b);\nrollback;\n\nIf the temporary table is created on a hard drive partition which is\nencrypted using dm_crypt, then under memory pressure, approximately\n30-40% of the time, pgsql will issue the above failure.\n\nThis patch should fix this problem, and the problem will come back if\nthe file system is mounted with the mblk_io_submit mount option.\n\nReported-by: Jon Nelson \u003cjnelson@jamponi.net\u003e\nSigned-off-by: \"Theodore Ts\u0027o\" \u003ctytso@mit.edu\u003e\n"

This depends on sb-\u003es_fs_info being filled, but we don\u0027t\nfill that in until we get to btrfs_fill_super, so we could hit supers on the\nfs_type super list that have a null s_fs_info. In order to fix that we need to\ngo ahead and setup a blank root with a blank fs_info to hold fs_devices, that\nway our test will work out right and then we can set s_fs_info in\nbtrfs_set_super, and then open_ctree will simply use our pre-allocated root and\nfs_info when setting everything up.
