| H A D | resize.c | 1d0c3924 Sat Feb 15 15:40:37 CST 2020 Theodore Ts'o <tytso@mit.edu> ext4: fix potential race between online resizing and write operations
During an online resize an array of pointers to buffer heads gets
replaced so it can get enlarged. If there is a racing block
allocation or deallocation which uses the old array, and the old array
has gotten reused this can lead to a GPF or some other random kernel
memory getting modified.
