gfs2: hide error messages after withdraw

2026-04-07T20:20:00+00:00

In gfs2_evict_inode(), don't issue error messages once a withdraw has already occurred. Signed-off-by: Andreas Gruenbacher

gfs2: wait for withdraw earlier during unmount

2026-04-07T20:20:00+00:00

During an unmount, wait for potential withdraw to complete before calling gfs2_make_fs_ro(). This will allow gfs2_make_fs_ro() to skip much of its work. Signed-off-by: Andreas Gruenbacher

gfs2: fix address space truncation during withdraw

2026-04-07T20:19:59+00:00

When a withdrawn filesystem's inodes are being evicted, the address spaces of those inodes still need to be truncated but we can no longer start new transactions. We still don't want gfs2_invalidate_folio() to race with gfs2_log_flush(), so take a read lock on sdp->sd_log_flush_lock in that case. (It may not be obvious, but gfs2_invalidate_folio() is a jdata-only address space operation.) Signed-off-by: Andreas Gruenbacher

gfs2: Fix data loss during inode evict

2026-03-23T19:55:27+00:00

When gfs2_evict_inode() is called on an inode with unwritten data in the page cache, the page cache needs to be written before it can be truncated. This doesn't always happen. Fix that by changing gfs2_evict_inode() to always either call evict_linked_inode() or evict_unlinked_inode(). Inside evict_unlinked_inode(), first check if the inode is dirty. If it is, make sure the inode glock is held and write back the data and metadata. If it isn't, skip those steps. Also, make sure that gfs2_evict_inode() calls gfs2_evict_inode() and evict_unlinked_inode() only if ip->i_gl is not NULL; this avoids unnecessary complications there. Fixes xfstest generic/211.

gfs2: minor evict_[un]linked_inode cleanup

2026-03-23T19:55:27+00:00

Add gl helper variables in evict_unlinked_inode() and evict_linked_inode(). This patch isn't very interesting by itself, but it makes the next patch more readable. Signed-off-by: Andreas Gruenbacher

gfs2: Avoid unnecessary transactions in evict_linked_inode

2026-03-23T19:55:24+00:00

In evict_linked_inode(), the truncate_inode_pages() calls are carried out inside a transaction. This code was added to what was then function gfs2_delete_inode() in commit 16615be18cadf ("[GFS2] Clean up journaled data writing"). These transactions are only used for creating revokes for the jdata buffers in the journal, so don't create such transactions when we know that the address space doesn't contain any jdata buffers for this inode and truncate the metadata address space outside of the transaction.

gfs2: Remove unnecessary check in gfs2_evict_inode

2026-02-24T17:22:51+00:00

We are no longer using LM_FLAG_TRY or LM_FLAG_TRY_1CB during inode evict, so ret cannot be GLR_TRYFAILED here. Signed-off-by: Andreas Gruenbacher

Convert 'alloc_obj' family to use the new default GFP_KERNEL argument

This was done entirely with mindless brute force, using git grep -l '\
