Descriptions

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

f2fs: fix to avoid potential deadlock

Using f2fs_trylock_op() in f2fs_write_compressed_pages() to avoid potential
deadlock like we did in f2fs_write_single_data_page().

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: f2fs: corrección para evitar un posible interbloqueo Usando f2fs_trylock_op() en f2fs_write_compressed_pages() para evitar un posible interbloqueo como lo hicimos en f2fs_write_single_data_page().
