| * PCI: only save/restore existent registers in the PCIe capabilityYu Zhao2009-04-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PCIe 1.1 base neither requires the endpoint to implement the entire PCIe capability structure nor specifies default values of registers that are not implemented by the device. So we only save and restore registers that must be implemented by different device types if the device PCIe capability version is 1. PCIe 1.1 Capability Structure Expansion ECN and PCIe 2.0 requires all registers in the PCIe capability to be either implemented or hardwired to 0. Their PCIe capability version is 2.

Unfortunately, neither the author, nor the committers seemed to know that we already have somewhere to do that -- pcibios_fixup_bus(). This patch moves the hook (used only by the K8 code) into x86-specific code where it should have been in the first place.

| * | Btrfs: look for acls during btrfs_read_locked_inodeChris Mason2009-04-27
| | | | | | | | | | | | | | | | | | | | | | | | This changes btrfs_read_locked_inode() to peek ahead in the btree for acl items. If it is certain a given inode has no acls, it will set the in memory acl fields to null to avoid acl lookups completely. Signed-off-by: Chris Mason <chris.mason@oracle.com>
| * | Btrfs: fix acl cachingChris Mason2009-04-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Linus noticed the btrfs code to cache acls wasn't properly caching a NULL acl when the inode didn't have any acls. This meant the common case of no acls resulted in expensive btree searches every time the kernel checked permissions (which is quite often). This is a modified version of Linus' original patch: Properly set initial acl fields to BTRFS_ACL_NOT_CACHED in the inode. This forces an acl lookup when permission checks are done. Fix btrfs_get_acl to avoid lookups and locking when the inode acls fields are set to null. Fix btrfs_get_acl to use the right return value from __btrfs_getxattr when deciding to cache a NULL acl. It was storing a NULL acl when __btrfs_getxattr return -ENOENT, but __btrfs_getxattr was actually returning -ENODATA for this case. Signed-off-by: Chris Mason <chris.mason@oracle.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A small warning popped up on ia64 because inode-map.c was comparing a u64 object id with the ULL FIRST_FREE_OBJECTID. My first thought was that all the OBJECTID constants should contain the u64 cast because btrfs code deals entirely in u64s. But then I saw how large that was, and figured I'd just fix the max() call.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Btrfs has printks for various IO errors, including bad checksums and mismatches between what we expect the block headers to contain and what we actually find on the disk.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, we updated a device's size prior to attempting a shrink operation. This patch moves the device resizing logic to only happen if the shrink completes successfully. In the process, it introduces a new field to btrfs_device -- disk_total_bytes -- to track the on-disk size.

| * | Btrfs: fix deadlocks and stalls on dead root removalChris Mason2009-04-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After a transaction commit, the old root of the subvol btrees are sent through snapshot removal. This is what actually frees up any blocks replaced by COW, and anything the old blocks pointed to. Snapshot deletion will pause when a transaction commit has started, which helps to avoid a huge amount of delayed reference count updates piling up as the transaction is trying to close. But, this pause happens after the snapshot deletion process has asked other procs on the system to throttle back a bit so that it can make progress. We don't want to throttle everyone while we're waiting for the transaction commit, it leads to deadlocks in the user transaction ioctls used by Ceph and makes things slower in general. This patch changes things to avoid the throttling while we sleep. Signed-off-by: Chris Mason <chris.mason@oracle.com>
| * | Btrfs: fix fallocate deadlock on inode extent lockChris Mason2009-04-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The btrfs fallocate call takes an extent lock on the entire range being fallocated, and then runs through insert_reserved_extent on each extent as they are allocated. The problem with this is that btrfs_drop_extents may decide to try and take the same extent lock fallocate was already holding. The solution used here is to push down knowledge of the range that is already locked going into btrfs_drop_extents. It turns out that at least one other caller had the same bug.

| * | Btrfs: try to keep a healthy ratio of metadata vs data block groupsJosef Bacik2009-04-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch makes the chunk allocator keep a good ratio of metadata vs data block groups. By default for every 8 data block groups, we'll allocate 1 metadata chunk, or about 12% of the disk will be allocated for metadata. This can be changed by specifying the metadata_ratio mount option. This is simply the number of data block groups that have to be allocated to force a metadata chunk allocation. By making sure we allocate metadata chunks more often, we are less likely to get into situations where the whole disk has been allocated as data block groups.

We perhaps should flag the filesystem as being corrupted if we see a special file (named pipes, device nodes, Unix domain sockets, etc.) with the EXTENTS_FL flag, but e2fsck doesn't currently check this case, so we'll just ignore this for now, since it's harmless. Without this fix, a special device with the extents flag is flagged as an error by the kernel, so it is impossible to access or delete the inode, but e2fsck doesn't see it as a problem, leading to confused/frustrated users.

So when we read in the inode, make sure the i_file_acl value is legal, and if not, flag the filesystem as being corrupted. Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
