From: "Michael S. Tsirkin" <mst@mellanox.co.il> Event queue handling performance improvements: - Only calculate EQ entry address once, and don't truncate the consumer index until we really need to. - Only read ECR once. If a new event occurs while we're in the interrupt handler, we'll get another interrupt anyway, since we only clear events once. Signed-off-by:

From: "Michael S. Tsirkin" <mst@mellanox.co.il> We don't need to write to the ECR to clear events when using MSI-X, since we never read the ECR anyway. Signed-off-by:

Continue development of Arbel Mem-Free support: we now compute a valid profile, allocate context memory, map sufficient aux memory for HCA page tables, map sufficient context memory to cover all reserved firmware resources and successfully call the INIT_HCA and QUERY_ADAPTER firmware commands. Fix a few error gotos that unwound the wrong things. Signed-off-by:

Slightly tidy up Andi Kleen's compat_ioctl conversion for the InfiniBand MAD driver by removing the no-longer-needed include of ioctl32.h, killing unreachable code and doing some really anal whitespace fixing. Signed-off-by:

Add optional callback before each device gets suspended (called 'presuspend'). Rename existing callback used by dm-mirror from 'suspend' to 'postsuspend'. dm-multipath will use the new callback. (Any kernel module using device-mapper must be recompiled after this patch.) Signed-Off-By:

Adds a boot parameter which can be used to specify a delay (in seconds) before the root device is decoded/discovered/mounted. Example usage for 10 second delay: rootdelay=10 Useful for usb-storage devices which no longer make their partitions immediately available, and for other storage devices which require some "spin-up" time.

This fixes a "no sound" problem with Wolfenstein Enemy Territory and (apparently) other games using the Quake3 engine. It probably affects some other OSS applications as well. This recreates some code that had been removed from the i810_audio driver around 5/2004. (This is the 2.6-based version of this patch.) Acked-by:

This patch removes the arbitrary limit of 32 acl entries on ext[23] when writing acls. A patch that removes the same check when reding acls is in BK since 12 March 2004, so all kernels since then are already able to read large acls. I think that ten+ months are enough so that we can now also remove the write limit. This is the read-limit patch: http://linux.bkbits.net:8080/linux-2.6/cset%404051e2863UsuQEgAQShmimgBooAXkg?nav=index.html Even without this patch the xattr block could already contain less space than needed for the acl, because other attributes might already use up almost all space. So this patch does not introduce additional error conditions. We have been shipping with this patch the last year (almost). Signed-off-by:

When a new inode is created, ext3_new_inode sets the EXT3_STATE_NEW flag, which tells ext3_do_update_inode to zero out the inode before filling in the inode's data. When a file is created in a directory with a default acl, the new inode inherits the directory's default acl; this generates attributes. The attributes are created before ext3_do_update_inode is called to write out the inode. In case of in-inode attributes, the new inode's attributes are written, and then zeroed out again by ext3_do_update_inode. Bad thing. Fix this by recognizing the EXT3_STATE_NEW case in ext3_xattr_set_handle, and zeroing out the inode there already when necessary. Signed-off-by:

When creating a filesystem with inodes bigger than 128 bytes, mke2fs fails to clear out bytes beyond EXT3_GOOD_OLD_INODE_SIZE in all inodes it creates (the journal, the filesystem root, and lost+found). We would require a zeroed-out i_extra_isize field but we don't get it, so disallow in-inode attributes for those inodes. Add an i_extra_isize sanity check. Signed-off-by:

We are checking for (EXT3_SB(inode->i_sb)->s_inode_size <= EXT3_GOOD_OLD_INODE_SIZE) to find out if we can set in-inode attributes; the test fails for inodes that have been created before the ea-in-inode patch. Those inodes have (i_extra_isize == 0), so we end up with the attributes overlapping the i_extra_isize field. Checking for (i_extra_isize == 0) instead fixes this case. The EXT3_STATE_XATTR flag is only set if (i_extra_isize > 0) and the inodes has in-inode attributes, so that is enough in the first two tests. Signed-off-by:

We found strange blocks layout in our mail server, after careful study, we got the reason and tried to fix it. On the very fist attempt to allocate a block to the newly-initialised inode, if we are trying to add a block at logical file offset "1" then ext2_find_goal() will incorrectly assume that this was a next_alloc_block cache hit (because we think the previously-allocated block was at offset zero). Net result: why trying to extend a freshly-opened one-block file we end up deciding to place the second file block at disk block "1", rather than going off and calling ext2_find_near(). Fix it by checking that we actually do have something valid cached in next_alloc_goal. Signed-off-by:
