Subject: refactor: migrate diskfs to inode_operations
X-Git-Url: https://projects.tadryanom.me/?a=commitdiff_plain;h=cc5b278349e96c4a7c3de68d86f5dd960e99b23c;p=AdrOS.git

refactor: migrate diskfs to inode_operations

- diskfs_dir_iops: lookup, readdir, create, mkdir, unlink, rmdir,
  rename, link (moved from diskfs_dir_fops)
- diskfs_file_iops: truncate (moved from diskfs_file_fops)
- diskfs_dir_fops: only close remains
- diskfs_file_fops: only read, write, close remain
- All node creation sites wire both f_ops and i_ops

20/20 smoke tests pass.
