* ocfs2: Trivial cleanup of jbd compatibility layer removalSunil Mushran2009-11-131-5/+0
| | | | | | | | | Mainline commit 53ef99cad9878f02f27bb30bc304fc42af8bdd6e removed the JBD compatibility layer from OCFS2. This patch removes the last remaining remnants of that. Signed-off-by: Sunil Mushran <sunil.mushran@oracle.com> Signed-off-by: Joel Becker <joel.becker@oracle.com>
* ocfs2: move ip_created_trans to struct ocfs2_caching_infoJoel Becker2009-09-041-1/+3
| | | | | | | | | | | | | Similar ip_last_trans, ip_created_trans tracks the creation of a journal managed inode. This specifically tracks what transaction created the inode. This is so the code can know if the inode has ever been written to disk. This behavior is desirable for any journal managed object. We move it to struct ocfs2_caching_info as ci_created_trans so that any object using ocfs2_caching_info can rely on this behavior. Signed-off-by: Joel Becker <joel.becker@oracle.com>
* ocfs2: move ip_last_trans to struct ocfs2_caching_infoJoel Becker2009-09-041-3/+19
| | | | | | | | | | | | We have the read side of metadata caching isolated to struct ocfs2_caching_info, now we need the write side. This means the journal functions. The journal only does a couple of things with struct inode. This change moves the ip_last_trans field onto struct ocfs2_caching_info as ci_last_trans. This field tells the journal whether a pending journal flush is required. Signed-off-by: Joel Becker <joel.becker@oracle.com>
* ocfs2: Take the inode out of the metadata read/write paths.Joel Becker2009-09-041-45/+38
| | | | | | | | | We are really passing the inode into the ocfs2_read/write_blocks() functions to get at the metadata cache. This commit passes the cache directly into the metadata block functions, divorcing them from the inode. Signed-off-by: Joel Becker <joel.becker@oracle.com>
* ocfs2: Change metadata caching locks to an operations structure.Joel Becker2009-09-041-44/+85
| | | | | | | | | We don't really want to cart around too many new fields on the ocfs2_caching_info structure. So let's wrap all our access of the parent object in a set of operations. One pointer on caching_info, and more flexibility to boot. Signed-off-by: Joel Becker <joel.becker@oracle.com>
* ocfs2: Make the ocfs2_caching_info structure self-contained.Joel Becker2009-09-041-48/+51
| | | | | | | | | | | | We want to use the ocfs2_caching_info structure in places that are not inodes. To do that, it can no longer rely on referencing the inode directly. This patch moves the flags to ocfs2_caching_info->ci_flags, stores pointers to the parent's locks on the ocfs2_caching_info, and renames the constants and flags to reflect its independant state.

* ocfs2: use smaller counters in ocfs2_remove_xattr_clusters_from_cacheMark Fasheh2008-10-131-1/+1
| | | | | | | i and b_len don't really need to be u64's. Xattr extent lengths should be limited by the VFS, and then the size of our on-disk length field. Signed-off-by: Mark Fasheh <mfasheh@suse.com>
* ocfs2: Switch over to JBD2.Joel Becker2008-10-131-1/+5
| | | | | | | | | | | | | | | | | | | | | | ocfs2 wants JBD2 for many reasons, not the least of which is that JBD is limiting our maximum filesystem size. It's a pretty trivial change. Most functions are just renamed. The only functional change is moving to Jan's inode-based ordered data mode. It's better, too. Because JBD2 reads and writes JBD journals, this is compatible with any existing filesystem. It can even interact with JBD-based ocfs2 as long as the journal is formated for JBD. We provide a compatibility option so that paranoid people can still use JBD for the time being. This will go away shortly.

* ocfs2: Add helper function in uptodate.c for removing xattr clustersTao Ma2008-10-131-6/+26
| | | | | | | | | The old uptodate only handles the issue of removing one buffer_head from ocfs2 inode's buffer cache. With xattr clusters, we may need to remove multiple buffer_head's at a time. Signed-off-by: Tao Ma <tao.ma@oracle.com> Signed-off-by: Mark Fasheh <mfasheh@suse.com>
* mm: Remove slab destructors from kmem_cache_create().Paul Mundt2007-07-201-1/+1
| | | | | | | | | | | | | | Slab destructors were no longer supported after Christoph's c59def9f222d44bb7e2f0a559f2906191a0862d7 change. They've been BUGs for both slab and slub, and slob never supported them either. This rips out support for the dtor pointer from kmem_cache_create() completely and fixes up every single callsite in the kernel (there were about 224, not including the slab allocator definitions themselves, or the documentation references).

* [PATCH] slab: remove kmem_cache_tChristoph Lameter2006-12-071-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Replace all uses of kmem_cache_t with struct kmem_cache. The patch was generated using the following script: #!/bin/sh # # Replace one string by another in all the kernel sources. # set -e for file in `find * -name "*.c" -o -name "*.h"|xargs grep -l $1`; do quilt add $file sed -e "1,\$s/$1/$2/g" $file >/tmp/$$ mv /tmp/$$ $file quilt refresh done The script was run like this sh replace kmem_cache_t "struct kmem_cache" Signed-off-by: Christoph Lameter <clameter@sgi.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* ocfs2: implement directory read-aheadMark Fasheh2006-09-201-2/+19
| | | | | | | | | | Uptodate.c now knows about read-ahead buffers. Use some more aggressive logic in ocfs2_readdir(). The two functions which currently use directory read-ahead are ocfs2_find_entry() and ocfs2_readdir(). Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
