Description
In the Linux kernel, the following vulnerability has been resolved:
f2fs: embed f2fs_gc_kthread in f2fs_sb_info
Instead of allocating f2fs_gc_kthread dynamically, embed it in
f2fs_sb_info. This simplifies lifetime management and prepares for
fixing race conditions during teardown.
- __sbi_store - remount|shutdown
- f2fs_stop_gc_thread
- access sbi->gc_thread
- sbi->gc_thread = NULL
- access sbi->gc_thread->f2fs_gc_task
