jbd2: don't leak memory if setting up journal fails
In journal_init_common(), if we failed to allocate the j_wbuf array, or if we failed to create the buffer_head for the journal superblock, we leaked the memory allocated for the revocation tables. Fix this. Cc: [email protected] # 4.9 Fixes: f0c9fd5 Signed-off-by: Eric Biggers <[email protected]> Signed-off-by: Theodore Ts'o <[email protected]> Reviewed-by: Jan Kara <[email protected]>
