2010-09-28GFS2: reserve more blocks for transactionsBenjamin Marzinski
Some of the functions in GFS2 were not reserving space in the transaction for the resource group header and the resource groups bitblocks that get added when you do allocation. GFS2 now makes sure to reserve space for the resource group header and either all the bitblocks in the resource group, or one for each block that it may allocate, whichever is smaller using the new gfs2_rg_blocks() inline function.

2010-08-09remove inode_setattrChristoph Hellwig
Replace inode_setattr with opencoded variants of it in all callers. This moves the remaining call to vmtruncate into the filesystem methods where it can be replaced with the proper truncate sequence. In a few cases it was obvious that we would never end up calling vmtruncate so it was left out in the opencoded variant: spufs: explicitly checks for ATTR_SIZE earlier btrfs,hugetlbfs,logfs,dlmfs: explicitly clears ATTR_SIZE earlier ufs: contains an opencoded simple_seattr + truncate that sets the filesize just above In addition to that ncpfs called inode_setattr with handcrafted iattrs, which allowed to trim down the opencoded variant.

2010-01-08GFS2: Fix gfs2_xattr_acl_chmod()Steven Whitehouse
The ref counting for the bh returned by gfs2_ea_find() was wrong. This patch ensures that we always drop the ref count to that bh correctly. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
2009-12-16sanitize xattr handler prototypesChristoph Hellwig
Add a flags argument to struct xattr_handler and pass it to all xattr handler methods. This allows using the same methods for multiple handlers, e.g. for the ACL methods which perform exactly the same action for the access and default ACLs, just using a different underlying attribute. With a little more groundwork it'll also allow sharing the methods for the regular user/trusted/secure handlers in extN, ocfs2 and jffs2 like it's already done for xfs in this patch. Also change the inode argument to the handlers to a dentry to allow using the handlers mechnism for filesystems that require it later, e.g. cifs.

2009-12-03GFS2: Clean up ACLsSteven Whitehouse
To prepare for support for caching of ACLs, this cleans up the GFS2 ACL support by pushing the xattr code back into xattr.c and changing the acl_get function into one which only returns ACLs so that we can drop the caching function into it shortly.

2009-12-03GFS2: Fix up system xattrsSteven Whitehouse
This code has been shamelessly stolen from XFS at the suggestion of Christoph Hellwig. I've not added support for cached ACLs so far... watch for that in a later patch, although this is designed in such a way that they should be easy to add.
