bcachefs: Run may_delete_deleted_inode() checks in bch2_inode_rm()

2025-06-10T11:17:09Z

commit 09fb85ae565645b982e9030dbb2ff6707f2cdddc upstream. We had a bug where bch2_evict_inode() incorrectly called bch2_inode_rm() - the journal clearly showed the inode was not unlinked. We've got checks that we use in recovery when cleaning up deleted inodes, lift them to bch2_inode_rm() as well. Signed-off-by: Kent Overstreet Signed-off-by: Greg Kroah-Hartman

bcachefs: delete dead code from may_delete_deleted_inode()

bcachefs: Fix casefold opt via xattr interface

2025-05-22T00:13:09Z

Changing the casefold option requires extra checks/work - factor out a helper from bch2_fileattr_set() for the xattr code to use. Signed-off-by: Kent Overstreet

bcachefs: Kill btree_iter.trans

2025-04-02T14:24:34Z

This was planned to be done ages ago, now finally completed; there are places where we have quite a few btree_trans objects on the stack, so this reduces stack usage somewhat. Signed-off-by: Kent Overstreet

bcachefs: bch2_disk_accounting_mod2()

2025-03-24T13:50:37Z

We're hitting some issues with uninitialized struct padding, flagged by kmsan. They appear to be falso positives, otherwise bch2_accounting_validate() would have flagged them as "junk at end". But for now, we'll need to initialize disk_accounting_pos with memset(). This adds a new helper, bch2_disk_accounting_mod2(), that initializes a disk_accounting_pos and does the accounting mod all at once - so overall things actually get slightly more ergonomic. BCH_DISK_ACCOUNTING_replicas keys are left for now; KMSAN isn't warning about them and they're a bit special. Signed-off-by: Kent Overstreet

bcachefs: EIO cleanup

2025-03-24T13:50:36Z

Replace these with proper private error codes, so that when we get an error message we're not sifting through the entire codebase to see where it came from. Signed-off-by: Kent Overstreet

bcachefs: Initialize from_inode members for bch_io_opts

2025-03-11T15:19:33Z

When there is no inode source, all "from_inode" members in the structure bhc_io_opts should be set false.

bcachefs: bcachefs_metadata_version_persistent_inode_cursors

2025-01-10T04:38:41Z

Persistent cursors for inode allocation. A free inodes btree would add substantial overhead to inode allocation and freeing - a "next num to allocate" cursor is always going to be faster. We just need it to be persistent, to avoid scanning the inodes btree from the start on startup. Signed-off-by: Kent Overstreet
