xfs: introduce realtime refcount btree ondisk definitions

2024-12-23T21:06:10Z

Add the ondisk structure definitions for realtime refcount btrees. The realtime refcount btree will be rooted from a hidden inode so it needs to have a separate btree block magic and pointer format. Next, add everything needed to read, write and manipulate refcount btree blocks. This prepares the way for connecting the btree operations implementation, though the changes to actually root the rtrefcount btree in an inode come later. Signed-off-by: "Darrick J.

xfs: create a shadow rmap btree during realtime rmap repair

2024-12-23T21:06:09Z

Create an in-memory btree of rmap records instead of an array. This enables us to do live record collection instead of freezing the fs. Signed-off-by: "Darrick J. Wong" Reviewed-by: Christoph Hellwig

xfs: add block headers to realtime bitmap and summary blocks

2024-11-05T21:38:40Z

Upgrade rtbitmap and rtsummary blocks to have self describing metadata like most every other thing in XFS. Signed-off-by: Darrick J. Wong Reviewed-by: Christoph Hellwig

xfs: define the format of rt groups

2024-11-05T21:38:39Z

Define the ondisk format of realtime group metadata, and a superblock for realtime volumes. rt supers are conditionally enabled by a predicate function so that they can be disabled if we ever implement zoned storage support for the realtime volume. For rt group enabled file systems there is a separate bitmap and summary file for each group and thus the number of bitmap and summary blocks needs to be calculated differently.

xfs: enable block size larger than page size support

2024-09-03T13:00:52Z

Page cache now has the ability to have a minimum order when allocating a folio which is a prerequisite to add support for block size > page size.

xfs: hoist new inode initialization functions to libxfs

xfs: implement atime updates in xfs_trans_ichgtime

Enable xfs_trans_ichgtime to change the inode access time so that we can use this function to set inode times when allocating inodes instead of open-coding it. Signed-off-by: Darrick J. Wong Reviewed-by: Christoph Hellwig

xfs: move RT inode locking out of __xfs_bunmapi

2024-04-22T12:30:47Z

__xfs_bunmapi is a bit of an odd place to lock the rtbitmap and rtsummary inodes given that it is very high level code. While this only looks ugly right now, it will become a problem when supporting delayed allocations for RT inodes as __xfs_bunmapi might end up deleting only delalloc extents and thus never unlock the rt inodes. Move the locking into xfs_bmap_del_extent_real just before the call to xfs_rtfree_blocks instead and use a new flag in the transaction to ensure that the locking happens only once.
