[PATCH v2 0/3] ovl: fix IS_APPEND() checks

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Miklos,

This series fixes the append-only violations found by the new
xfstest overlay/030.

I got rid of the wrong patch to convert sb_start_write() to
file_start_write() and moved the open flag checks into
ovl_d_real().

Amir.

v2:
- move open check to ovl_d_real()
- discard wrong patch to file_start_write() in ftruncate()

v1:
- fix checks in [f]truncate and vfs_open()

Amir Goldstein (3):
  vfs: ftruncate check IS_APPEND() on real inode
  vfs: truncate check IS_APPEND() on real inode
  ovl: check IS_APPEND() on real upper inode
