2008-11-01saner FASYNC handling on file closeAl Viro
As it is, all instances of ->release() for files that have ->fasync() need to remember to evict file from fasync lists; forgetting that creates a hole and we actually have a bunch that *does* forget. So let's keep our lives simple - let __fput() check FASYNC in file->f_flags and call ->fasync() there if it's been set. And lose that crap in ->release() instances - leaving it there is still valid, but we don't have to bother anymore.

2008-10-09block: unify request timeout handlingJens Axboe
Right now SCSI and others do their own command timeout handling. Move those bits to the block layer. Instead of having a timer per command, we try to be a bit more clever and simply have one per-queue. This avoids the overhead of having to tear down and setup a timer for each command, so it will result in a lot less timer fiddling.

2008-08-16[SCSI] megaraid_sas: remove sysfs dbg_lvl world writeable permissionsJoe Malicki
/sys/bus/pci/drivers/megaraid_sas/dbg_lvl defaults to being world-writable, which seems bad (letting any user affect kernel driver behavior and logging level).

2008-04-29[SCSI] megaraid_mbox: fix Dell CERC firmware problemHannes Reinecke
Newer Dell CERC firmware (>= 6.62) implement a random deletion handling compatible with the legacy megaraid driver. The legacy handling shifted the target ID by 0x80 only for I/O commands (READ/WRITE/etc), whereas megaraid_mbox shifts the target ID always if random deletion is supported. The resulted in megaraid_mbox sending an INQUIRY to the wrong channel, and not finding any devices, obviously. So we disable the random deletion support if the offending firmware is found.

2008-02-11[SCSI] MegaRAID driver management char device moved to miscThomas Horsten
The MegaRAID driver's common management module (megaraid_mm.c) creates a char device used by the management tool "megarc" from LSI Logic (and possibly other management tools). In 2.6 with udev, this device doesn't get created because it is not registered in sysfs. I first fixed this by registering a class "megaraid_mm", but realized that this should probably be moved to misc devices, instead of taking up a char major. This is because only 1 device is used, even if there are multiple adapters - the minor is never used (the adapter info is in the ioctl block sent to the driver, not detected based on the minor number as one might think). So it is a complete waste to have an entire major taken by this. So it now uses a misc device which I named "megadev0" (the name that megarc expects), and has a dynamic minor (previoulsy a dynamic major was used). I have tested this on my own system with the megarc tool, and it works just as fine as before (only now the device gets created correctly by udev).

2007-05-21Detach sched.h from mm.hAlexey Dobriyan
First thing mm.h does is including sched.h solely for can_do_mlock() inline function which has "current" dereference inside. By dealing with can_do_mlock() mm.h can be detached from sched.h which is good. See below, why. This patch a) removes unconditional inclusion of sched.h from mm.h b) makes can_do_mlock() normal function in mm/mlock.c c) exports can_do_mlock() to not break compilation d) adds sched.h inclusions back to files that were getting it indirectly. e) adds less bloated headers to some files (asm/signal.h, jiffies.h) that were getting them indirectly Net result is: a) mm.h users would get less code to open, read, preprocess, parse, ... if they don't need sched.h b) sched.h stops being dependency for significant number of files: on x86_64 allmodconfig touching sched.h results in recompile of 4083 files, after patch it's only 3744 (-8.3%).
