The OnStream SCSI Tape driver uses a semaphore as mutex. Use the mutex API instead of the (binary) semaphore.

The following patch adds support for sysfs/uevent modalias attribute for scsi devices (like disks, tapes, cdroms etc), based on whatever current sd.c, sr.c, st.c and osst.c drivers supports. The modalias format is like this: scsi:type-0x04 (for TYPE_WORM, handled by sr.c now). Several comments. o This hexadecimal type value is because all TYPE_XXX constants in include/scsi/scsi.h are given in hex, but __stringify() will not convert them to decimal (so it will NOT be scsi:type-4). Since it does not really matter in which format it is, while both modalias in module and modalias attribute match each other, I descided to go for that 0x%02x format (and added a comment in include/scsi/scsi.h to keep them that way), instead of changing them all to decimal. o There was no .uevent routine for SCSI bus. It might be a good idea to add some more ueven environment variables in there. o osst.c driver handles tapes too, like st.c, but only SOME tapes. With this setup, hotplug scripts (or whatever is used by the user) will try to load both st and osst modules for all SCSI tapes found, because both modules have scsi:type-0x01 alias). It is not harmful, but one extra module is no good either. It is possible to solve this, by exporting more info in modalias attribute, including vendor and device identification strings, so that modalias becomes something like scsi:type-0x12:vendor-Adaptec LTD:device-OnStream Tape Drive and having that, match for all 3 attributes, not only device type. But oh well, vendor and device strings may be large, and they do contain spaces and whatnot. So I left them for now, awaiting for comments first.

Many struct file_operations in the kernel can be "const". Marking them const moves these to the .rodata section, which avoids false sharing with potential dirty data. In addition it'll catch accidental writes at compile time to these shared resources.

- check all sysfs-related return codes, and propagate them back to callers - properly unwind errors in osst_probe(), init_osst(). This fixes a leak that occured if scsi driver registration failed, and fixes an oops if sysfs creation returned an error.

another signdness warning from gcc 4.1 drivers/scsi/osst.c:5154: warning: comparison of unsigned expression < 0 is always false The problem is that blk is defined as unsigned, but all usages of it are normal int cases. osst_get_frame_position() and osst_get_sector() return ints and can return negative values. If blk stays an unsigned int, the error check is useless.

Pass the POSIX lock owner ID to the flush operation. This is useful for filesystems which don't want to store any locking state in inode->i_flock but want to handle locking/unlocking POSIX locks internally. FUSE is one such filesystem but I think it possible that some network filesystems would need this also. Also add a flag to indicate that a POSIX locking request was generated by close(), so filesystems using the above feature won't send an extra locking request in this case.

Be warned, that beyond compiling, and checking that the new module doesn't immediately blow up, there hasn't yet been a lot of testing. But this should allow you to comment on the changes, and move forward with dropping scsi_request from the kernel code.

As devfs has been disabled from the kernel tree for a number of months now (5 to be exact), here's a patch against 2.6.16-rc1-git1 that removes support for it from the SCSI subsystem.

This should eliminate (at least in the mid layer) to make numeric assumptions about any of the enumeration variables. As a side effect, it will also make all the messages consistent and line us up nicely for the error logging strategy (if it ever shows itself again).

This patch does a full cleanup of 'NULL checks before vfree', and a partial cleanup of calls to kfree for all of drivers/ - the kfree bit is partial in that I only did the files that also had vfree calls in them. The patch also gets rid of some redundant (void *) casts of pointers being passed to [vk]free, and a some tiny whitespace corrections also crept in.

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!
