cifs: add fscache_resize_cookie() to cifs_setsize()
Several code paths update the VFS inode size by calling
netfs_resize_file() and cifs_setsize(), but omit the corresponding
fscache_resize_cookie() call, leaving the fscache cookie out of sync
with the actual file size:
- cifs_file_set_size() in inode.c: server-side truncation via setattr
- cifs_do_truncate() in file.c: truncates to zero on O_TRUNC open
- smb2_duplicate_extents() in smb2ops.c: file clone extending EOF
- smb3_simple_falloc() in smb2ops.c: two branches that extend EOF
via write-range and SMB2_set_eof respectively
Since every caller of cifs_setsize() must resize the fscache cookie,
add the call to cifs_setsize() itself, consistent with how
truncate_pagecache() is already consolidated there.
Fixes: 70431bfd825d ("cifs: Support fscache indexing rewrite")
Fixes: 93a43155127f ("cifs: Fix missing set of remote_i_size")
Fixes: 110fee6b9bb5 ("smb: client: fix missing timestamp updates with O_TRUNC")
Fixes: 7a06d3b816d7 ("smb/client: emulate small EOF-extending mode 0 fallocate ranges")
