xfs: validate the realtime geometry in xfs_validate_sb_common

2020-03-27T15:32:53Z

Validate the geometry of the realtime geometry when we mount the filesystem, so that we don't abruptly shut down the filesystem later on. Signed-off-by: Darrick J. Wong Reviewed-by: Dave Chinner

xfs: remove the di_version field from struct icdinode

2020-03-19T15:48:47Z

We know the version is 3 if on a v5 file system. For earlier file systems formats we always upgrade the remaining v1 inodes to v2 and thus only use v2 inodes. Use the xfs_sb_version_has_large_dinode helper to check if we deal with small or large dinodes, and thus remove the need for the di_version field in struct icdinode.

xfs: only check the superblock version for dinode size calculation

2020-03-19T15:48:47Z

The size of the dinode structure is only dependent on the file system version, so instead of checking the individual inode version just use the newly added xfs_sb_version_has_large_dinode helper, and simplify various calling conventions.

xfs: add a new xfs_sb_version_has_v3inode helper

2020-03-19T15:47:34Z

Add a new wrapper to check if a file system supports the v3 inode format with a larger dinode core. Previously we used xfs_sb_version_hascrc for that, which is technically correct but a little confusing to read. Also move xfs_dinode_good_version next to xfs_sb_version_has_v3inode so that we have one place that documents the superblock version to inode version relationship.

xfs: support bulk loading of staged btrees

2020-03-18T15:12:23Z

Add a new btree function that enables us to bulk load a btree cursor. This will be used by the upcoming online repair patches to generate new btrees. This avoids the programmatic inefficiency of calling xfs_btree_insert in a loop (which generates a lot of log traffic) in favor of stamping out new btree blocks with ordered buffers, and then committing both the new root and scheduling the removal of the old btree blocks in a single transaction commit. The design of this new generic code is based off the btree rebuilding code in xfs_repair's phase 5 code, with the explicit goal of enabling us to share that code between scrub and repair. It has the additional feature of being able to control btree block loading factors. Signed-off-by: Darrick J. Wong Reviewed-by: Brian Foster

xfs: introduce fake roots for inode-rooted btrees

2020-03-18T15:12:23Z

Create an in-core fake root for inode-rooted btree types so that callers can generate a whole new btree using the upcoming btree bulk load function without making the new tree accessible from the rest of the filesystem. It is up to the individual btree type to provide a function to create a staged cursor (presumably with the appropriate callouts to update the fakeroot) and then commit the staged root back into the filesystem.
