* libata: only call ->done once all per-tag ressources are releasedChristoph Hellwig2015-10-121-9/+13
| | | | | | | | | | | | When calling ->done before releasing resources we could run into a race where the SCSI midlayer sends another command and races with the resources beeing manipulated. For libata this can't currently happen as synchronization happens at a higher level, but I'd still like to fix it to future proof libata and to avoid copy & paste into SCSI drivers where this pattern has led to reproducible crashes.

* ata: ahci: find eSATA ports and flag them as removableManuel Lauss2015-09-304-2/+15
| | | | | | | | | | | | | | | | | | If the AHCI ports' HPCP or ESP bits are set, the port should be considered external (e.g. eSATA) and is marked as removable. Userspace tools like udisks then treat it like an usb drive. With this patch applied, when I plug a drive into the esata port, KDE pops up a window asking what to do with the drives(s), just like it does for any random USB stick. Removability is indicated to the upper layers by way of the SCSI RMB bit, as I haven't found another way to signal userspace to treat a sata disk like any usb stick.

* ata: pata_pxa: dmaengine conversionRobert Jarzmik2015-09-101-112/+59
| | | | | | | | | | | | The PXA architecture was offered a slave dmaengine support. As a consequence the direct DMA registers are progressively replaced by dmaengine support. This makes the pata_pxa change, which brings this driver to almost a generic ATA 40-wires driver relying on dmaengine for transfers.

* ahci: added a new driver for supporting Freescale AHCI sataTang Yuantian2015-09-083-0/+282
| | | | | | | | | | | | | | Currently Freescale QorIQ series SATA is supported by ahci_platform driver. Some SoC specific settings have been put in uboot. So whether SATA works or not heavily depends on uboot. This patch will add a new driver to support QorIQ sata which removes the dependency on any other boot loader. Freescale QorIQ series sata, like ls1021a ls2085a ls1043a, is compatible with serial ATA 3.0 and AHCI 1.3 specification.

| | | | | | | | | | | | | | | | | This reverts commit 5163fb62541e ("ahci: added support for Freescale AHCI sata") The reverted patch added Freescale QorIQ AHCI sata support to ahci_platform driver though, but it left SoC specific settings to uboot. It leads to QorIQ sata heavily depending on uboot. In order to removing the dependency we first revert the old patch and then will add a new driver for QorIQ SATA. Since there are no LS* platforms that have been upstreamed, So the revert would not break anything exists.

| * NFSv4: Respect the server imposed limit on how many changes we may cacheTrond Myklebust2015-09-075-11/+55
| | | | | | | | | | | | | | | | | | | | | | The NFSv4 delegation spec allows the server to tell a client to limit how much data it cache after the file is closed. In return, the server guarantees enough free space to avoid ENOSPC situations, etc. Prior to this patch, we assumed we could always cache aggressively after close. Unfortunately, this causes problems with servers that set the limit to 0 and therefore do not offer any ENOSPC guarantees. Signed-off-by: Trond Myklebust <trond.myklebust@primarydata.com>

This commit causes a NFSv4 regression in that close()+unlink() can end up failing. The reason is that we no longer have a guarantee that the CLOSE has completed on the server, meaning that the subsequent call to REMOVE may fail with NFS4ERR_FILE_OPEN if the server implements Windows unlink() semantics.

| | | | | | | | | | | | | | | | | | | | | | | | | | If a read-write layout has an invalid mirror, then we should mark it as invalid, and return it. If a read-only layout has an invalid mirror, then mark it as invalid and check if there is still at least one valid mirror before we return it.

| | | | | | | | | | | | | | | | | | | | | | | | | | According to RFC5661 Section 18.2.4, CLOSE is supposed to return the zero stateid. This means that nfs_clear_open_stateid_locked() cannot assume that the result stateid will always match the 'other' field of the existing open stateid when trying to determine a race with a parallel OPEN.
