* xfs: push down inactive transaction mgmt for remote symlinksBrian Foster2013-10-081-1/+1
| | | | | | | | | | | | | Push down the transaction management for remote symlinks from xfs_inactive() down to xfs_inactive_symlink_rmt(). The latter is cleaned up to avoid transaction management intended for the calling context (i.e., trans duplication, reservation, item attachment).

* xfs: split out the remote symlink handlingDave Chinner2013-08-121-41/+1
| | | | | | | | | | | | The remote symlink format definition and manipulation needs to be shared with userspace, but the in-kernel interfaces do not. Split the remote symlink format handling out into xfs_symlink_remote.[ch] fo it can easily be shared with userspace.

* xfs: sync minor header differences needed by userspace.Dave Chinner2013-08-121-1/+2
| | | | | | | | | | | Little things like exported functions, __KERNEL__ protections, and so on that ensure user and kernel shared headers are identical.

* xfs: fix the symbolic link assert in xfs_ifreeMark Tinguely2013-06-191-1/+1
| | | | | | | | | | | | | 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: add CRC checks to remote symlinksDave Chinner2013-04-271-3/+31
| | | | | | | | | | | | | | | Add a header to the remote symlink block, containing location and owner information, as well as CRCs and LSN fields. This requires verifiers to be added to the remote symlink buffers for CRC enabled filesystems. This also fixes a bug reading multiple block symlinks, where the second block overwrites the first block when copying out the link name.

* xfs: split out symlink code into it's own file.Dave Chinner2013-04-211-0/+38
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.
