From 241fc4367b3ca5d407b043599ed980304a70b91f Mon Sep 17 00:00:00 2001 From: Russell King Date: Wed, 27 Jul 2005 11:35:54 +0100 Subject: [SERIAL] Expose 8250_pci setup/removal/suspend/resume functions Re-jig the setup/removal/suspend/resume of 8250 pci ports so that they know slightly less about how they're attached to a PCI device. Expose this as the new interface for registering PCI serial ports, as well as the pciserial_board structure and associated flag definitions.

It does this since an NFSv3/v4 exclusive create cannot immediately set the mode bits. The 01777 mode then gets put into the inode->i_mode. After the file creation is successful, we then do a setattr to change the mode to the correct value (as per the NFS spec). The problem is that nfs_refresh_inode() no longer updates inode->i_mode, so the latter retains the 01777 mode. A bit later, the VFS notices this, and calls remove_suid(). This of course now resets the file mode to inode->i_mode & 0777. Hey presto, the file mode on the server is now magically changed to 0777. Duh...

Using bitops means we can use a generic wait_on_bit call instead of an ad hoc locking scheme in fs/nfs/inode.c, so we can remove the "nfs_i_wait" field from nfs_inode at the same time. The other new flags field will continue to use bitmask and logic AND and OR. This permits several flags to be set at the same time efficiently. The following patch adds a spin lock to protect these flags, and this spin lock will later cover other fields in the nfs_inode structure, amortizing the cost of using this type of serialization. Test plan: Millions of fsx ops on SMP clients.

To do this, we need to protect the fields in the nfs_inode structure adequately. Start by serializing updates to the "cache_validity" field. Note this change addresses an SMP hang found by njw@osdl.org, where processes deadlock because nfs_end_data_update and nfs_revalidate_mapping update the "cache_validity" field without proper serialization. Test plan: Millions of fsx ops on SMP clients. Run Nick Wilson's breaknfs program on large SMP clients.

This bug could cause oopses and page state corruption, because ncpfs used the generic page-cache symlink handlign functions. But those functions only work if the page cache is guaranteed to be "stable", ie a page that was installed when the symlink walk was started has to still be installed in the page cache at the end of the walk. We could have fixed ncpfs to not use the generic helper routines, but it is in many ways much cleaner to instead improve on the symlink walking helper routines so that they don't require that absolute stability. We do this by allowing "follow_link()" to return a error-pointer as a cookie, which is fed back to the cleanup "put_link()" routine. This also simplifies NFS symlink handling.

This is because libata interrupt handler is unaware that interrupts are not expected during that period. This patch adds ATA_FLAG_NOINTR flag to tell the interrupt handler that we're not expecting interrupts. Note that once proper HSM is implemented for interrupt-driven PIO, this should be merged into it and this flag will be removed. ahci.c is a different kind of beast, so it's left alone. * The following drivers use ata_qc_issue_prot and ata_interrupt, so changes in libata core will do. ata_piix sata_sil sata_svw sata_via sata_sis sata_uli * The following drivers use ata_qc_issue_prot and custom intr handler.

Since mod_devicetable.h is included both from kernel and from host build helper, we may be in trouble if we are building on 32bit host for 64bit target - userland sees unsigned long long, kernel sees unsigned long and while their sizes match, alignments might not. Fixed by forcing alignment. Fortunately, almost nobody else needs that - the rest of such fields is naturally aligned as it is. * of_device_id has void * in it. Host userland helpers need kernel_ulong_t instead, since their void * might have nothing to do with the kernel one. Fixed in the same way it's done for similar problems in pcmcia_device_id (ifdef __KERNEL__). * pcmcia_device_id has the same problem as ieee1394_device_id. Fixed the same way.
