| * | | | [SCSI] qla2xxx: Fix to allow to reset devices using sg interface (sg_reset).Vladislav Bolkhovitin2006-08-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently it is impossible to reset provided by Qlogic QLA2xxx driver SCSI devices externally using corresponding sg devices, particularly via sg_reset utility, because qla2xxx driver in qla2xxx_eh_device_reset() function checks if the input scsi_cmnd has its private data (CMD_SP()) attached. Then the found pointer isn't used anywhere inside of qla2xxx_eh_device_reset(). If the RESET request comes from sg device, it doesn't have such private data. The attached patch removes check for non-NULL CMD_SP() from qla2xxx_eh_device_reset(), hence allows to reset QLA2xxx's devices using corresponding sg devices. AV: change applies to bus/host reset handlers as well.

With patch, the driver access PCIconfiguration space with dedicated offset to read a signature. If the signature read, it means that the controller has capability to handle 64-bit DMA. Without this patch, the driver used to blindly claim 64-bit DMA capability. The issue has been reported by Vasily Averin [vvs@sw.ru]. Thank you Vasily for the reporting.

If a connection is dropped and reconnected while an abort is running then we should assume the recovery code will clean up the abort. Not doing so causes a oops. And if a command completes then we get the status for the abort, we do not need to call into the LLD to cleanup the resources. Doing this causes and oops in iser because it ends up freeing some resources twice. Signed-off-by: Mike Christie <michaelc@cs.wisc.edu> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

Currently, if the server returns a bitmap or attr length that causes the current decode point pointer to wrap, this could go undetected (consider a small "negative" length on a 32-bit machine). Also add a check into the main XDR decode handler to make sure that the amount of data is a multiple of four bytes (as specified by RFC-1014). This makes sure that we can do u32* pointer subtraction in the NFS client without risking an undefined result (the result is undefined if the pointers are not correctly aligned with respect to one another).

| * | | | | VFS: add lookup hint for network file systemsASANO Masahiro2006-08-24

A typical mkdir(2) calls two inode_operations: lookup and mkdir. The lookup operation would fail with ENOENT in common case. I think it is unnecessary because the subsequent mkdir operation can check it. In case of creat(2), lookup operation is called with the LOOKUP_CREATE flag, so individual filesystem can omit real lookup. e.g. nfs_lookup(). Here is a sample patch which uses LOOKUP_CREATE and O_EXCL on mkdir, symlink and mknod. This uses the gadget for creat(2). And here is the result of a benchmark on NFSv3. mkdir(2) 10,000 times: original 50.5 sec patched 29.0 sec Signed-off-by: ASANO Masahiro <masano@tnes.nec.co.jp> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com> (cherry picked from fab7bf44449b29f9d5572a5dd8adcf7c91d5bf0f commit)

Fix possible deadlock by analyzing gfp mask and refusing to release page if __GFP_FS is not set.

| * | | | | | [PATCH] sata_via: use old SCR access pattern on vt6420Tejun Heo2006-08-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | vt6420 has super-fragile SCR registers which can hang the whole machine if accessed with the wrong timings. This patch makes sata_via use SCR registers only during probing and with the same timings as before (pre new EH), which is proven to work.

If 1, PCS is ignored, 2 honored. As there seem to be quite a few ICHs w/ impaired PCS, this option will be useful for cases where the default setting doesn't work.

Analysis shows that these problems are caused by bogus PCS values from those controllers. Before the PCS update, the driver didn't honor PCS regs exactly and probed them in many cases PCS reports no device. Now that PCS is honored exactly, these hardware problems are visible. This patch makes ICH5 ignore PCS. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
