tree-wide: s/struct fileattr/struct file_kattr/g

2025-07-04T14:14:39+00:00

Now that we expose struct file_attr as our uapi struct rename all the internal struct to struct file_kattr to clearly communicate that it is a kernel internal struct. This is similar to struct mount_{k}attr and others. Link: https://lore.kernel.org/20250703-restlaufzeit-baurecht-9ed44552b481@brauner Signed-off-by: Christian Brauner

ext2: convert to the new mount API

2025-02-24T16:02:37+00:00

Convert ext2 to the new mount API. Note that this makes the sb= option more accepting than it was before; previosly, sb= was only accepted if it was the first specified option. Now it can exist anywhere, and if respecified, the last specified value is used. Parse-time messages here are sent to ext2_msg with a NULL sb, and ext2_msg is adjusted to accept that, as ext4 does today as well.

quota: Properly annotate i_dquot arrays with __rcu

2024-02-08T11:04:59+00:00

Dquots pointed to from i_dquot arrays in inodes are protected by dquot_srcu. Annotate them as such and change .get_dquots callback to return properly annotated pointer to make sparse happy. Fixes: b9ba6f94b238 ("quota: remove dqptr_sem") Signed-off-by: Jan Kara

ext2: Convert ext2_unlink() and ext2_rename() to use folios

2023-10-25T18:31:29+00:00

This involves changing ext2_find_entry(), ext2_dotdot(), ext2_inode_by_name(), ext2_set_link() and ext2_delete_entry() to take a folio. These were also the last users of ext2_get_page() and ext2_put_page(), so remove those at the same time.

ext2: improve consistency of ext2_fsblk_t datatype usage

2023-08-18T10:54:54+00:00

The ext2 block allocation/deallocation functions and their respective calls use a mixture of unsigned long and ext2_fsblk_t datatypes to index the desired ext2 block. This commit replaces occurrences of unsigned long with ext2_fsblk_t, covering the functions ext2_new_block(), ext2_new_blocks(), ext2_free_blocks(), ext2_free_data() and ext2_free_branches(). This commit is rather conservative, and only replaces unsigned long with ext2_fsblk_t if the variable is used to index a specific ext2 block.
