Debian patch for aufs on 2.6.29
|
|
|
|
---
|
|
|
|
Add support for Kernel 2.6.29.
|
|
|
|
Changes we are affected by:
|
|
1. dentry_open() receives a new argument for passing the cred
|
|
2. current->fsuid is now current_fsuid()
|
|
3. disable security_inode_* calls, as they are not exported normally. Enable
|
|
them only if CONFIG_AUFS_SEC_PERM_PATCH is defined
