Subject: xfs: Add support for multi rtgroup shrink+removal
Date: Thu, 19 Feb 2026 11:27:37 +0530 [thread overview]
Message-ID: <20260219055737.769860-1-nirjhar@linux.ibm.com> (raw)
Hi all,
This series adds online support for shrinking and removing multiple
realtime groups in XFS.
Currently, realtime group shrink/removal operations are not available.
This series extends the infrastructure to allow online shrinking/removal of
multiple rtgroups in a single operation.
The work is organized into three sub-patchsets:
1. Kernel changes
- Core filesystem changes enabling multi-rtgroup shrink/removal.
2. xfsprogs updates
- Changes to xfs_growfs allow the shrink requests to be passed to the kernel.
3. fstests additions
- Test coverage validating grow, shrink and removal of multiple rtgroups.
Each patch includes details describing the implementation and design considerations.
Comments and reviews are greatly appreciated.
