Description OSIDB Bzimport 2025-12-09 02:02:00 UTC 
In the Linux kernel, the following vulnerability has been resolved:

f2fs: synchronize atomic write aborts

To fix a race condition between atomic write aborts, I use the inode
lock and make COW inode to be re-usable thoroughout the whole
atomic file inode lifetime.
