Description OSIDB Bzimport 2024-10-21 13:04:30 UTC

In the Linux kernel, the following vulnerability has been resolved:

f2fs: fix to wait dio completion

It should wait all existing dio write IOs before block removal,
otherwise, previous direct write IO may overwrite data in the
block which may be reused by other inode.
