xfs: kill xfs_vnodeops.[ch]

2013-08-12T21:53:39+00:00

Now we have xfs_inode.c for holding kernel-only XFS inode
operations, move all the inode operations from xfs_vnodeops.c to
this new file as it holds another set of kernel-only inode
operations. The name of this file traces back to the days of Irix
and it's vnodes which we don't have anymore.

Essentially this move consolidates the inode locking functions
and a bunch of XFS inode operations into the one file. Eventually
the high level functions will be merged into the VFS interface
functions in xfs_iops.c.

This leaves only internal preallocation, EOF block manipulation and
hole punching functions in vnodeops.c. Move these to xfs_bmap_util.c
where we are already consolidating various in-kernel physical extent
manipulation and querying functions.

xfs: create xfs_bmap_util.[ch]

2013-08-12T21:45:17+00:00

There is a bunch of code in xfs_bmap.c that is kernel specific and
not shared with userspace. To minimise the difference between the
kernel and userspace code, shift this unshared code to
xfs_bmap_util.c, and the declarations to xfs_bmap_util.h.

The biggest issue here is xfs_bmap_finish() - userspace has it's own
definition of this function, and so we need to move it out of
xfs_bmap.[ch]. This means several other files need to include
xfs_bmap_util.h as well.

It also introduces and interesting dance for the stack switching
code in xfs_bmapi_allocate(). The stack switching/workqueue code is
actually moved to xfs_bmap_util.c, so that userspace can simply use
a #define in a header file to connect the dots without needing to
know about the stack switch code at all.

xfs: reshuffle dir2 definitions around for userspace

2013-08-12T21:40:57+00:00

Many of the definitions within xfs_dir2_priv.h are needed in
userspace outside libxfs. Definitions within xfs_dir2_priv.h are
wholly contained within libxfs, so we need to shuffle some of the
definitions around to keep consistency across files shared between
user and kernel space.

xfs: separate dquot on disk format definitions out of xfs_quota.h

2013-08-12T21:09:52+00:00

The on disk format definitions of the on-disk dquot, log formats and
quota off log formats are all intertwined with other definitions for
quotas. Separate them out into their own header file so they can
easily be shared with userspace.

xfs: Add pquota fields where gquota is used.

2013-07-11T15:35:32+00:00

Add project quota changes to all the places where group quota field
is used:
   * add separate project quota members into various structures
   * split project quota and group quotas so that instead of overriding
     the group quota members incore, the new project quota members are
     used instead
   * get rid of usage of the OQUOTA flag incore, in favor of separate
     group and project quota flags.
   * add a project dquot argument to various functions.

Not using the pquotino field from superblock yet.

xfs: fix the symbolic link assert in xfs_ifree

2013-06-19T19:14:43+00:00

Adding an extended attribute to a symbolic link can force that
link to an remote extent. xfs_inactive() incorrectly assumes
that any symbolic link small enough to be in the inode core
is incore, resulting in the remote extent to not be removed.
xfs_ifree() will assert on presence of this leaked remote extent.

xfs: fix rounding in xfs_free_file_space

2013-05-20T19:25:50+00:00

The offset passed into xfs_free_file_space() needs to be rounded
down to a certain size, but the rounding mask is built by a 32 bit
variable. Hence the mask will always mask off the upper 32 bits of
the offset and lead to incorrect writeback and invalidation ranges.

This is not actually exposed as a bug because we writeback and
invalidate from the rounded offset to the end of the file, and hence
the offset we are actually punching a hole out of will always be
covered by the code. This needs fixing, however, if we ever want to
use exact ranges for writeback/invalidation here...

xfs: split out symlink code into it's own file.

2013-04-21T20:38:04+00:00

The symlink code is about to get more complicated when CRCs are
added for remote symlink blocks. The symlink management code is
mostly self contained, so move it to it's own files so that all the
new code and the existing symlink code will not be intermingled
with other unrelated code.

xfs: take inode version into account in XFS_LITINO

2013-03-14T21:19:14+00:00

Add a version argument to XFS_LITINO so that it can return different values
depending on the inode version.  This is required for the upcoming v3 inodes
with a larger fixed layout dinode.
