It breaks\nhigh-order pages previously allocated for non-dio transfer.\n\nThis patches adds reserved_page_order to st_buffer structure to save\npage order for non-dio transfer.\n\nhttp://bugzilla.kernel.org/show_bug.cgi?id\u003d14563\n\nWhen enlarge_buffer() allocates 524288 from 0, st uses six-order page\nallocation. So mdata-\u003epage_order is 6 and frp_seg is 2.\n\nAfter that, if st uses dio, sgl_map_user_pages() sets\nmdata-\u003epage_order to 0 for st_do_scsi(). After that, when we call\nnormalize_buffer(), it frees only free frp_seg * PAGE_SIZE (2 * 4096)\nthough we should free frp_seg * PAGE_SIZE \u003c\u003c 6 (2 * 4096 \u003c\u003c 6). So we\nsee buffer_size is set to 516096 (524288 - 8192).\n\nReported-by: Joachim Breuer \u003clinux-kernel@jmbreuer.net\u003e\nTested-by: Joachim Breuer \u003clinux-kernel@jmbreuer.net\u003e\nAcked-by: Kai Makisara \u003ckai.makisara@kolumbus.fi\u003e\nSigned-off-by: FUJITA Tomonori \u003cfujita.tomonori@lab.ntt.co.jp\u003e\nCc: stable@kernel.org\nSigned-off-by: James Bottomley \u003cJames.Bottomley@suse.de\u003e\n"

      "message": "[SCSI] drivers/scsi/st.c: add reference count and related fixes\n\nI have rediffed the patch against 2.6.13-rc5, done a couple of cosmetic\ncleanups, and run some tests.  Brian King has acknowledged that it fixes the\nproblems he has seen. Seems mature enough for inclusion into 2.6.14 (or\nlater)?\n\nNate\u0027s explanation of the changes:\n\nI\u0027ve attached patches against 2.6.13rc2. These are basically identical\nto my earlier patches, as I found that all issues I\u0027d seen in earlier\nkernels still existed in this kernel.\n\nTo summarize, the changes are: (more details in my original email)\n\n- add a kref to the scsi_tape structure, and associate reference\ncounting stuff\n\n- set sr_request-\u003eend_io \u003d blk_end_sync_rq so we get notified when an IO\nis rejected when the device goes away\n\n- check rq_status when IOs complete, else we don\u0027t know that IOs\nrejected for a dead device in fact did not complete\n\n- change last_SRpnt so it\u0027s set before an async IO is issued (in case\nst_sleep_done is bypassed)\n\n- fix a bogus use of last_SRpnt in st_chk_result\n\nSigned-off-by: Nate Dailey \u003cnate.dailey@stratus.com\u003e\nSigned-off-by: Kai Makisara \u003ckai.makisara@kolumbus.fi\u003e\nSigned-off-by: James Bottomley \u003cJames.Bottomley@SteelEye.com\u003e\n"
