From e9d8e2bf23206825ca9b4d3caf587945ba807939 Mon Sep 17 00:00:00 2001 From: Taotao Chen Date: Wed, 16 Jul 2025 09:36:06 +0000 Subject: fs: change write_begin/write_end interface to take struct kiocb * Change the address_space_operations callbacks write_begin() and write_end() to take struct kiocb * as the first argument instead of struct file *. Update all affected function prototypes, implementations, call sites, and related documentation across VFS, filesystems, and block layer. Part of a series refactoring address_space_operations write_begin and write_end callbacks to use struct kiocb for passing write context and flags.
