quota: Properly invalidate caches even for filesystems with blocksize < pagesize Sometimes invalidate_bdev() can fail to invalidate a part of block device cache because of dirty data. If the filesystem has blocksize smaller than page size, this can happen even for pages containing quota files and thus kernel would operate on stale data. Fix the issue by syncing the filesystem before invalidating the cache. Reviewed-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Jan Kara <jack@suse.cz>
