Remove PageReserved() calls from core code by tightening VM_RESERVED handling in mm/ to cover PageReserved functionality. PageReserved special casing is removed from get_page and put_page. All setting and clearing of PageReserved is retained, and it is now flagged in the page_alloc checks to help ensure we don't introduce any refcount based freeing of Reserved pages. MAP_PRIVATE, PROT_WRITE of VM_RESERVED regions is tentatively being deprecated. We never completely handled it correctly anyway, and is be reintroduced in future if required (Hugh has a proof of concept). Once PageReserved() calls are removed from kernel/power/swsusp.c, and all arch/ and driver code, the Set and Clear calls, and the PG_reserved bit can be trivially removed. Last real user of PageReserved is swsusp, which uses PageReserved to determine whether a struct page points to valid memory or not. This still needs to be addressed (a generic page_is_ram() should work). A last caveat: the ZERO_PAGE is now refcounted and managed with rmap (and thus mapcounted and count towards shared rss). These writes to the struct page could cause excessive cacheline bouncing on big systems. There are a number of ways this could be addressed if it is an issue.

The previous patch adding the ability to nest struct class_device changed the paramaters to the call class_device_create(). This patch fixes up all in-kernel users of the function. Signed-off-by: NGreg Kroah-Hartman <gregkh@suse.de>

This fixes an issue in scsi command initialization from a request where sd, sr, st, and scsi_lib all fail to copy the request's cmd_len to the scsi command's cmd_len field. Signed-off-by: NTimothy Thelin <timothy.thelin@wdc.com> Signed-off-by: NJames Bottomley <James.Bottomley@SteelEye.com>

reported by Doug Gilbert and fixed by him in sg.c (see [PATCH] sg direct io/mmap oops). Doug fixed the comparison in sg.c. This fix for st.c does not touch the comparison but makes both arguments signed to remove the problem. The new code is adapted from linux/fs/bio.c.

I have rediffed the patch against 2.6.13-rc5, done a couple of cosmetic cleanups, and run some tests. Brian King has acknowledged that it fixes the problems he has seen. Seems mature enough for inclusion into 2.6.14 (or later)? Nate's explanation of the changes: I've attached patches against 2.6.13rc2. These are basically identical to my earlier patches, as I found that all issues I'd seen in earlier kernels still existed in this kernel. To summarize, the changes are: (more details in my original email) - add a kref to the scsi_tape structure, and associate reference counting stuff - set sr_request->end_io = blk_end_sync_rq so we get notified when an IO is rejected when the device goes away - check rq_status when IOs complete, else we don't know that IOs rejected for a dead device in fact did not complete - change last_SRpnt so it's set before an async IO is issued (in case st_sleep_done is bypassed) - fix a bogus use of last_SRpnt in st_chk_result Signed-off-by: NNate Dailey <nate.dailey@stratus.com> Signed-off-by: NKai Makisara <kai.makisara@kolumbus.fi> Signed-off-by: NJames Bottomley <James.Bottomley@SteelEye.com>

Removing the SCSI tape module results in an oops in class_device_destroy if any devices are present. The patch at the end of this message fixes the bug by moving class_destroy() later in exit_st() so that the class still exists when devices are removed. (The bug is old but class_simple_device_remove() did nothing when the class did not exist.) The patch also fixes a "class leak" in init_st() error path. I would like to get this into 2.6.13 but it may be too late? Signed-off-by: NKai Makisara <kai.makisara@kolumbus.fi> Signed-off-by: NJames Bottomley <James.Bottomley@SteelEye.com>

This patch is against 2.6.12-rc3 + linus-patch from April 30. The patch contains the following fixes: - CAP_SYS_RAWIO is used instead of CAP_SYS_ADMIN; fix from Alan Cox - only direct sending of SCSI commands requires this permission - the st status is modified is successful unload is performed using SCSI_IOCTL_STOP_UNIT Signed-off-by: NKai Makisara <kai.makisara@kolumbus.fi> Signed-off-by: NJames Bottomley <James.Bottomley@SteelEye.com>

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
