[PATCH v4 3/5] fs: change write_begin/write_end interface to take struct kiocb *

陈涛涛 Taotao Chen
2025-07-07T07:01:00Z

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.
