const: mark struct vm_struct_operations

2009-09-27T18:39:25+00:00

* mark struct vm_area_struct::vm_ops as const
* mark vm_ops in AGP code

But leave TTM code alone, something is fishy there with global vm_ops
being used.

ext4: Remove syncing logic from ext4_file_write

2009-09-14T15:08:16+00:00

The syncing is now properly handled by generic_file_aio_write() so
no special ext4 code is needed.

ext[234]: move over to 'check_acl' permission model

2009-09-08T18:09:04+00:00

Don't implement per-filesystem 'extX_permission()' functions that have
to be called for every path component operation, and instead just expose
the actual ACL checking so that the VFS layer can now do it for us.

ext4: update the s_last_mounted field in the superblock

2009-06-13T14:09:48+00:00

This field can be very helpful when a system administrator is trying
to sort through large numbers of block devices or filesystem images.
What is stored in this field can be ambiguous if multiple filesystem
namespaces are in play; what we store in practice is the mountpoint
interpreted by the process's namespace which first opens a file in the
filesystem.

ext4: Fix discard of inode prealloc space with delayed allocation.

2009-03-28T02:36:43+00:00

With delayed allocation we should not/cannot discard inode prealloc
space during file close. We would still have dirty pages for which we
haven't allocated blocks yet. With this fix after each get_blocks
request we check whether we have zero reserved blocks and if yes and
we don't have any writers on the file we discard inode prealloc space.

ext4: Automatically allocate delay allocated blocks on close

2009-02-24T13:21:14+00:00

When closing a file that had been previously truncated, force any
delay allocated blocks that to be allocated so that if the filesystem
is mounted with data=ordered, the data blocks will be pushed out to
disk along with the journal commit.  Many application programs expect
this, so we do this to avoid zero length files if the system crashes
unexpectedly.

ext4: Rename ext4dev to ext4

2008-10-11T00:02:48+00:00

The ext4 filesystem is getting stable enough that it's time to drop
the "dev" prefix.  Also remove the requirement for the TEST_FILESYS
flag.

Hook ext4 to the vfs fiemap interface.

2008-10-07T04:46:36+00:00

ext4_ext_walk_space() was reinstated to be used for iterating over file
extents with a callback; it is used by the ext4 fiemap implementation.
