When we do a flush of the AIL list, we are writing out what is
likely to be a lot of small I/Os, which are possibly in an order
which is not ideal performance-wise. Since this is done by calling
filemap_fdatatwrite for each individual inode's address space there
is no overall plugging going on.

ENOSPC was being returned in slot_get inspite of successful

A couple of int fields were being used as boolean values
so we can make them bitfields of one bit, and put them in
what might otherwise be a hole in the structure with 64
bit alignment.

This is another step towards improving the allocation of xattr
blocks at inode allocation time. Here we take advantage of
Christoph's recent work on ACLs to allocate a block for the
xattrs early if we know that we will be adding ACLs to the
inode later on. The advantage of that is that it is much

gfs2_lookupi() can return NULL if the path to the root is broken by
another rename/rmdir. In this case gfs2_ok_to_move() must check for
this NULL pointer and return error.

Add pr_fmt, remove embedded GFS2: prefixes.
This now consistently emits lower case gfs2: for each message.

Return -E2BIG rather than -EINVAL if hit the maximum size limits of

Upstream commit 34cc178 changed a line of code from calling function

If multiple nodes fail and their recovery work runs simultaneously, they
would use the same unprotected variables in the superblock. For example,
they would stomp on each other's revoked blocks lists, which resulted
in file system metadata corruption. This
This patch fixes a long standing issue in mapping the journal

and although the cache took account of that by merging extents,
it did not actually map large extents, but instead was doing a
block by block mapping. Since the journal was

When gfs2_create_inode() fails due to quota violation, the VFS
inode is not completely uninitialized. This can cause a list
corruption error.
This patch correctly uninitializes the VFS inode when a quota
violation occurs in the gfs2_create_inode codepath.
Now that rgrps use the address space which is part of the super
block, we need to update gfs2_mapping2sbd() to take account of
that. The only way to do that easily is to use a different set
of address_space_operations for rgrps.
