Dan Carpenter e121bd48b9 ext4: silence an uninitialized variable warning ... Smatch complains that "i" can be uninitialized if we don't enter the loop. I don't know if it's possible but we may as well silence this warning. [ Initialize i to sb->s_blocksize instead of 0. The only way the for loop could be skipped entirely is the in-memory data structures, in particular the bh->b_data for the on-disk superblock has gotten corrupted enough that calculated value of group is >= to ext4_get_groups_count(sb). In that case, we want to exit immediately without allocating a block. -- TYT ] Fixes: 8016e29f43 ("ext4: fast commit recovery path") Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Link: https://lore.kernel.org/r/20201030114620.GB3251003@mwanda Signed-off-by: Theodore Ts'o <tytso@mit.edu> Cc: stable@kernel.org		2020-11-06 22:52:36 -05:00
